[Q] SGS2 (i9100) USB Audio Out functionality - Galaxy S II Q&A, Help & Troubleshooting

Dear XDA people,
I have not found any conclusive topic on whether it's possible (or is already done) to enable USB audio output (to a DAC obviously) on the SGS2. Some shreds of relevant topics have crossed my path, but they all either died out or were for different models.
So: What is the status? What's the roadblock? Is there in fact already a rom/kernel which has this enabled?
Thanks
edit: There's a feature request on the Android project page, but I can't link to it due to <10 posts. The title is: Issue 24614: Enable USB audio on the Galaxy Nexus (or any Android 4.0 device)

Not currently possible & unlikely to be on the SGS2 tbh. Devs who have been asked to have a look at it have gone 'nup' & don't have the time/inclination to work on it (blame Samsung).
Only chance of it happening would be to code it yourself or for a dev who actually wants to use that functionality themselves to have a go at it. People have started threads on here where people have pledged X amount of $ if a dev can get this working, but these threads fall off the radar due to lack of interest fairly quickly & there have been no takers on the dev side.
I wouldn't hold your breath.

Right, that's sad to hear. No developers who want this? Strange... thought they'd be interested in getting the best possible out of the hardware available.
Guess I'll wait for future models then. Thanks for the clarification.

From the comments I've seen from the devs who have been asked, it's a case of not having to mess around with/spend a lot of time dealing with Samsung's ****ty closed source drivers etc. Take CM9 as an example, those guys have been doing that since the first ICS leaks were released late last yr & frankly I don't blame them for being fed up.
Most people don't realise exactly how much work goes into making things work on a custom rom (a real one; not a winzip job like 80% of 'roms' on here), getting this to work would not be a walk in the park.
And the other thing is many (most) people also have a dedicated media player which puts out much better sound than the SGS2 anyways.

Yeah don't get me wrong -- I appreciate the work that goes into messing with this stuff (especially the process of discovering how it actually works, the reverse engineering of sorts). I just thought that this was a pretty big feature to have and was surprised there was so little to find about it.
And yeah, I also have a better media player (Cowon D2), but the integration into a single device is the attractive part obviously, and unfortunately the SGS2 doesn't have the good audio chip that the SGS1 does have (Stupid Samsung).

Yep using the Yamaha chip in the SGS2 was a puzzling move given how universally praised the sound quality was on the SGS, and made even more puzzling by Samsung going back to a Wolfson chip on the SGS3. A moment of madness perhaps. Every review of the SGS3 I've read so far has said the sound quality is very good.

And that is exactly the reason why this feature should be enabled
There are quite a few people who enjoy high quality portable audio. Many of them use portable headphone amplifiers as standard headphone outputs on devices are quite often unable to properly drive high(er) end headphones. Many of these portable headphone amplifiers also have an USB DAC on board for use with a computer.
Being able to use USB Audio out on your phone would mean one less device to lug around. The quality of the Android devices audio components would no longer matter, as the external DAC/Amplifier would take over their function.
Just imagine, no more worries about what DAC is put in a phone, as you would be free to choose your own external DAC.
Galaxy S3 can do it, some tablets can do it, so hopefully someone will be inspired to make this happen on the S2 and other devices.

I hear the arguments & agree with you (I personally would use it), but it's very unlikely to happen for the SGS2. Samsung have made it very very difficult to do by way of the Yamaha sound chip & their ****ty closed source drivers/firmware, and devs who have been asked so far have looked at it & gone 'Nup'.
So, as I said in my post above, unless you find a dev with a fair bit of time on their hands who actually wants to use this themselves, it probably won't happen.
Edit - @Coop: Have a look at this post by Entropy in the CM9 thread re: proprietary code/the crap devs have to deal with. Just to give you a bit of background as to why the devs who have been asked to date have all said no.

Tv remote control

*update, the conclusion is that the current software is useless and as of the ppc6800 and the following HTC models, the IRDA port is either crap or non-existent, for that reason I am building a powered, universal adapter to turn any phone into a remote*
hello. first off, yes I know there are old threads about this, but they are dead and had a different take on this topic. I am looking to know if anyone has gotten any tv remote control software working on the mogul. I don't care about the distance so I dont want to hear about how the mogul is ill-equipped to do this, I just want to know what software works as I will use\make a IR repeater\booster that will give me all the range I need.
I have tried the following software
1-PDAWin tv remote controller simply crashes when I press any button
2- noviiRemote is not compatible with our IR
3- RemoteControl II v.2.12 stays it is incompatible with our processor and for that reason, it turns off the IR access... but the rest of the software works ??? odd
4- UniversalRemoteCE 4.0 Tested by wagonis, froze his phone with every try
5- Total Remote does not work, freezes when I try to record a signal.
Untested
6- UltraMote
can't find
7- VITO remote
so to recap. Has anyone found a working software? I will give a free IR booster\repeater to anyone who can point me to a proper and working programmable universal remote control software that works over IR and not the web (or even better, anyone who can get PDAWin tv remote working )
thanks.
Honestly, I've tried 4 different softwares from that list and none worked, if anything they kept crashing my phone...so I gave up before I caused any damage to my phone. If you figure out which one works though, please list it, I'd like to know and try it.
can I know which was teh 4th that did not work so I can update my list please?
UniversalRemoteCE 4.0 froze up my phone every time I tried to use it
Many have tried. I am pretty sure no one has succeeded.
in my best Airplane - The Movie voice
"good luck, we're all counting on you"
my best suggestion is to buy an older known compatible phone with stronger irda
i looked into it a bit ago and came up with a good solution and found two of the phones on ebay for $20...but never bought them
i know it would be convenient to use our daily cell for this feature...but its an uphill battle
dont give up...lol
double post
Since the whole software thing does not seem to work... I am going to set out on making my own! My goal is to make a universal-universal remote app; even cross-platform, and the way I will do this is with external hardware. Since most new phones do not have a good IR port, I will make an external IR port that plugs into phones, mark my words!
I will keep people up to date on this
I'll subscribe to this thread to keep tabs on this. Good luck.
Well I am very excited to say that things are moving along nicely. Unfortunately, my local electronics supply shop (that is actually worth going to) is closed during weekends since its a small business who's main clients are engineering students during the year . This means that My full prototype (with range booster) will have to wait, but the basic premise is working, and, depending on my schedule, I should have a working prototype soon. I have already gotten in contact with a few chinese companies to compare the price of production of the modules.
well, the project is coming along well, but I need some input from the community. 1 is a note, 2 is the important question.
1- the software will be open source. The exact format still has to be determined, but the main lead right now is java so that i can be universal for all phones (except the Iphone that will need its own app).
2- Should it be powered or not? The module is coming along well, but I need some input. If it is powered, I have to make the tough decision between having the ext-usb plug sticking out on the edge of the board, meaning you have a 9v battery dangling from your phone or a short cable (1-2 feet) that plugs in the ext-usb port and the module rests next to you. What is the best route for this? (Ideally I would love bluetooth, but I do not have the electronic know-how for this)

Why not make all? Powered and not. Corded and not. Are you encasing the electronics? If just for the Mogul how 'bout a phone case type add on putting the IR port on the right end of the phone while you're at it so we don't have to rotate our screens? That being said, with the Mogul getting dated, how 'bout for newer phones lacking IR ports all together like the touch pro and touch pro 2? Oh, maybe someone could help you out with bluetooth.
Well its not just for the mogul, it is going to work universally for all HTC phones and will be one little tweak away from working with other phones.
As far as corded or not, I think I will make it non corded and then you can just add it. It will cost a few cents extra but save alot on production costs of 2 different modules (if I go with powered, unpowered can easily be both).
The reason I am not doing powered and unpowered is that the powered requires a case and a battery and starts getting a little big (the size of half a thumb approximately), while the unpowered one is about 0.5mmx0.5mm. Also, making the powered one requires a much greater production cost as it would be made in china because if I make it myself, the powered one would be about 4 inches by 2 inches as I can't make the small traces myself, many of the parts are hard to come by and suftace mount is hard to do.
The reason that none of the programs work is because they require raw IR port access, not the IRDA protocol.

Thats ok, this is a hardware\software combination so the IR will work.

lol I hear ya. Everything is being delayed because the store I usually go to was selling IR LEDs for 4 bucks and they don't specify voltage so I had to order some online. I just need to get that stupid LED so that I can be done with the hardware and get working on the software.
I am still waiting on those diodes. I bought molding and casting material so that our IR emitters will look better than a loose set or components soldered on an extusb port
Anyone going to china who can buy ExtUSB ports for 50 cents with the breakout port? I got that quote from a company but I don't like sending unsecured payments and 10$ per extusb port + breakout board is going to make it pretty expensive for us. If so, let me know, I would like to buy a batch.
thanks.
since our device will work on many phones, instead of creating threads in every forum of every device, we decided to opt for a twitter account where we will keep everyone up to date on this project.

Found this thread searching for a Bluetooth to IR converter, so I could use my Rhodium as a universal remote.
I was wondering... since all modern smartphones have Bluetooth, why not make a powered BT -> IR converter, which uses the HID standard? Since most phones have a HID application already (my old SE K750i could be used to control my desktop computer with HID), you don't need a lot of development on the phones itself. You'd need a way to program the conversion table (key 5 -> send PLAY IR sequence), I guess. You could then have a simple HID remote on simple phones or a full blown custom skinnable remote on a WVGA smartphone.
It would really be nice to have a Philips Pronto (or similar) universal remote where you can operate all sorts of equipment.
unfortunately, working with bluetooth at that level would be well beyond my expertise and bring the cost up $$$$$ because of the low volume of production. Also, making the drivers for this would be much harder and way to phone-specific, killing the intent of this device. Also, the way this works, it should work with any standard IR device.
I have a p4000 and am upgrading to a touch pro2, when I upgrade again in 2 years, I don't want to have to start the project over .
Finally, bluetooth device = more components = bulkier and = batteries!
I am getting back home late tonight and I will get back to work on the project (got the LEDs the day I was leaving).
ps. I do appreciate all feedback and comments.
thank you

sorry for being off topic, but do you know when the touch pro 2 is coming out in Canada ? And who's gonna get it telus, roger, fido or bell ?? (hope this is coming to Telus)
hehe, its out with telus waiting for mine in the mail now!
Inbound Ir
Will your Module accept inbound ir transfer? I am using a polar hr monitor that uses ir to download files to my phone. I've been looking for an upgrade option with ir without success. If your module will work, this is great news. Keep up the good work.

DSLR Remote for Android ?

the Iphone works with an DSRL Remote app. I have an HTC HD2 and it works with winmobile 6 and with android now. Does somebody know an app which works on android or winmobile 6 like the DSRL Remote camcorder app ?
Greeting from Germany
Carsten
been thinking of that for some time now, would LOVE that. But I read somewhere that it may be a problem to use the USB port as host...
http://www.gphoto.org/ ?
i recently found out that it is possible to do this with a nintendo ds but it requires some DIY work or paying someone to do this for you, surprisingly even in germany there seem to be some people building these.
my uncle bought one of these cables/modules for his canon 5dmk2 a few weeks ago. since i got my hands on it I thought about how awesome such a feature would be (preferably wireless) on an a phone.
I would love something like that! An android phone would make the holy grail of dSLR remote controls. Time intervals, exposure settings, super-smooth HDRI with bracketing of multiple photos, live view, hell even motion activated shooting (figure out a way to detect motion from image through the live view and trigger a shutter release every time that happens).
Anyone up for this?! I'll be getting both my SGS and 5DMKII in about a month, super willing to beta-test
I'd love this too for Nikon Devices!

It is possible. Only drawback is that a laptop is needed like with the iphone app.
So a possible setup would be like this:
Camera <-> USB cable <-> Laptop running Linux <-> WLAN/Edge/3G <-> Android
The only big dislike is the laptop in that chain

It's the same setup used for the iPhone, it's basically a remote control setup and I can't really see how it helps that much, it feels like more of a gimmick rather than something helpful since you still need to carry a laptop with you.
Now, if the camera could be directly connected to the phone, that'd be awesome, since you pretty much carry a phone with you at all times.

That's the point. It is not possible... well, everything is, but the effort cannot be worth the outcome.
It is more likely to do it with an Arduino board with Wlan chip and USB host.
But then again, you have to reverse engineer the Nikon and Canon protocols or use the linux library.... Should be possible, but you need to buy some hardware anyway.
Check this:

Cheap plug-computers like sheevaplug or this one: http://www.ionicsplug.com/cumulus.html would make it kind of easy as they run linux, have USB connector(s) and have WLAN (sheevaplug needs USB WLAN stick).
Cross-compiling gphoto library, writing a software which talks through gphoto to the cam and report the capabilities back to the connected Android / Iphone.
Only (major) drawback is that those plug computers need a power supply. I have seen someone running sheevaplug with solar panel .
Sheevaplug is around 75€, so quite affordable.
I need to connect my 5DM2 and check whether things like touch-focus, live preview and stuff would be possible...
What do you think about the power plug issue?
Hehe, I like how you assumed that I can understand these things I dont
At work atm but will try to read through the article, but as I understand so far, this guy uses a small linux computer that can communicate through a WLAN adapter so you basically have a wifi remote control. Looks pretty darn cool, especially for the money, and using a solar panel would be awesome!
Only thing is that it doesn't have that much to do with android as far as I can tell, if it's a web interface then you can use it with any device, right?
What I was thinking was more in the likes of a replacement for the $100+ timer triggers with your phone. I think it should be possible but maybe people wouldn't invest in it (though I think they should).
BTW, I just remembered that you can also trigger the camera through the headphone jack, as with those diy remote releases. Do you think there could be a way to use the SGS headphone jack to cause shutter releases? You wouldn't get any control of the settings from the phone, but you could still program time intervals or bulb shots! Hey, even motion sensing shots, provided you dock your phone some place. And you have to admit it doesn't sound too difficult, right?
See the diy thing here: http://www.instructables.com/id/Rem...or-Canon-Cameras/step2/Cut-off-the-ear-peice/
If/when someone does make something like this, I would think a small netbook would be sufficiently portable, compared to a 15" or 17" laptop, to use as the "host" device.

I see. The thing is there are ready to use solutions out there which do exactly what you are requesting.
My approach was a different one. I wanted to be able to mount the camera somewhere, connect sheevaplug, then go somewhere and remotely control the camera in every aspect. Imaging you have to shoot a marriage. You could place the camera somewhere, take a seat somewhere and see exactly the live-view image from the camera, can point somewhere on the touchscreen to focus on that point, control exposure settings and hit the button to take the shot.
That was my approach. If I would be able to achieve this just with a sheevaplug computer for 75€, that would be great. But there still is the issue with the power necessary to run the computer.
Another problem would be to gain the time needed to write the app. I am able to do that, but time is rare...
I can understand the appeal, as I said it would be awesome to have such a setup, just not for me so far. I'll try to understand how the shutter release works through the remote and report here, i think the headphone jack would be really nice considering that no amount of extra equipment would be necessary, apart from the cable.
Just a quick question, why would you require any coding on the phone, why not use a VNC-like application and install the official canon application on windows?

have you ever tried to watch a movie through a VNC connection?
Sheevaplug is driven by a Marvell ARM CPU, no x86 which would be needed by Windows. So only possible way would be to install linux with virtualization, setup windows XP in a container, install EOS software and a VNC server, then use a crappy VNC client on Android to control my camera? Sounds like a crappy setup to me
Having a small, slick and performant native UI would be muuuuuuch better.
I personally don't think that you will succeed with this headphone jack thingie. But I wish you good luck
Hehe, thanks
Good luck with ur project.
Lookie what I just found...
Googling aroud on more general terms for this topic, i found someone pointing to libgPhoto, a multi platform camera control lib: *crap, cannot post links, wtf*
*edit* google for libGphoto, it also has a remote.
Looking a bit further, i came across this:
google for : gitorious agphoto2 commits / master
Now i haven't found any more info on the project yet, but this looks like a project that some of us here on XDA could maybe join in on.. The only problem that then remains is the usb-usb cable There's an actual start on porting an existing lib available!
Just to keep this discussion running (I am not a programmer).
Take a look at:

Play Guitar through you phone app for Android?

Hi!
This might sounds silly but do you guys know if anyone is working on something like this for android?
http://www.youtube.com/watch?v=0Nod69aTzsM
An app that makes your phone to a small guitar amp?
The iphone version has been out for a while but i cant find any info on a version for android..
The company behind iRig have been speaking about a android version but i dont think they even have started working on one yet.
It would be a really nice application! To allways be ready to record without setting up the computor and stuff like that ya know, or to just sit in the sofa with earplugs and play some sweet solos and riffs without having your gf whine about the loud music..
Found this dude trying to make something close. http://www.youtube.com/watch?v=sz-9mxWa2VA
Just checking if anyone knows anything?
Best regards and thx for all the awsomeness!
/Patrik
This would be awesome, I would definitely buy it. It's like a Line 6 pod but much cheaper.
I hope they're working on an android version. Android needs better quality apps.
Also, it's more of a multi-effect pedal than an amp. Just letting you know
I actually sent then a message on youtube to see if they were working on one. This is what I got.
This is the Mac/PC version. If you look at our AmpliTube iRig playlist you'll find the iPhone version. We're currently looking at the platform but do not have any versions for Android.
Sent from my Nexus One using XDA App
Yeah, multi-effect pedal.
Imageing all the fine stuff you could do with it!
You could use it as an effect to plug in to your amp. (maby quite alot of effects, if you can make your own sounds. And with new developing you never have to buy a new effect-pedal again.. ).
A strummer for electric guitar in the studio/rehearsal place.
Play with earplugs on the sofa.
and so on...
I'll buy!!
it needs dedicated hardware don't forget (about 10 seconds in on the video)
your phone only has one 3.5mm jack plug...and you need to plug a guitar into it and an amp into it too.
also, what happens if you've got your amp turned up to 11 and then you get a phone call?

I've bookmarked that link
I am amazed that this can be done on the iPhone but not on Android.
There is another program called Ghettoamp on the market, though the devloper admits that there is still latency (he records, then processes the sound input). 20ms I think.

Android phones definitely have the processing power to do this. The only real problem is you're input and outputs on your phone, there's really only one... the 3.5 mm jack...
But there's maybe a way around this. And I'm not an engineer or developer or genius of any kind I'm just saying what I think should be at least possible... Everyone knows AD2P Bluetooth right? You could get you're input through it.
You use the microphone of a bluetooth headset, but instead of the microphone, you get your input from you're amp/guitar/whatever... could it be as simple as soldering a headphone jack to the PCB connections on a bluetooth headset? Dunno but let's asume it's possible.
Then you connect your phone to the headset, and you've got input... Great.
The problem now is that I don't know what android does when it has a bluetooth headset AND a normal set of earphones... Does it play from both, does it by default choose, I don't know... Say you still get output from the headphones, you could easily get the output to any speakers, seems rather pointless to use the phone's loudspeaker... This part from bluetooth input to audio jack output will maybe need a modified audio driver or something...
Once you've got input into the phone and output out of the phone, you would like to have some effects and/or amplification right? That's the point isn't it? I know nothing about programming such things but maybe a few developers who do will stumble onto this thread and share their expertise...
Once again it should be possible, but for just anyone to do this it'll be very challenging, more likely and hopefully companies like Gibson or Marshall or Ibanez (their Japanese, and this seems like a Japanese thing to do) for instance will see the need for something like this, and get working on it... If they make something like that and it works well, it'll make a LOT of money... For instance after you've bought this device, they could SELL effects, to be downloaded on a sort of 'plugin-basis'. And once one company does it, all will have some variant of the concept. I know I'd buy this...
Edit: Read about the apparent latency issue that Android has... So I don't know if it's that possible just yet, maybe ICS has bettered this flaw in previous Android versions, one can only hope...
Sorry for refreshing this thread, but I'm curious if there is such app for android available right now?

You are thinking much too complicated.
The headphone jack of phones contains another pin for the microphone. A small jumper cable can be used that allows the connection of a guitar and headphones. Check out Amplitube iRig for an example.
(this type of jack is used so you can plug in a headset with microphone)
Bluetooth or something would be nice... but the latency wouldn't be, and that is exactly the problem.. Android has too much latency,
Look:
http://code.google.com/p/android/issues/detail?id=3434
Android is not capable of this because the way it handles audio is completely wrong. More recent devices have less latency but still too much. The problem lies very deep. It is a problem for game developers too. Please star this issue if you want Google to do something about it!
Send with my telegraph
How about USB OTG connected to a Rocksmith USB connection?...

The Irig will work fine for this you dont need bluetooth aor usb adding yet another layer of BS to the audio streams round trip. however now that JB is out latancy is stitting around 10-12ms on adevice such as the galaxy nexus wich is completely usable (1ms of latancy = 1foot from your amp) so 12ms would be like playing 12 feet from your amp,
If you cant play like this then on stage will never work for you.
As a side note usb audio is apparently supported in JB as well now
There are now a couple of apps on Android that at least have a range of guitar effects. Delay Effects Plus (via headphone type cable) and usbEffects (USB OTG) both have an option to use Native Audio, so if you have the Galaxy Nexus running JB the latency is quite reasonable (50-70 mSec). If you have a modded ROM you may get lower latency without Native Audio option as they both read the buffer size from the OS. Of course for everyone else the latency is still an issue and varies from device to device. So to those that said they would buy .... please do!
This very issue has put me on the fence on what kind of tablet I buy. Cannot decide between note, and Ipad 3. The accessories and ItunesU has been one of the biggest attractions for me.
Litlle heads up: in their latest newsletter IK Multimedia (of Amplitube) post a few job openings, one of them being "Android App Developer"!
So they are at least working on something..

[Q] Is there a root available for the Xtrons TD730a Double Din Headunit?

Hi there,
I hope I'm posting this request in the right section.
I have recently bought myself an Xtrons TD730a Double Din Head Unit, I would post a link to it but unfortunately I am unable to as the forum won't let me. You should be able to find the unit in question with the help of google though.
On the whole I've been pretty happy with the device. The main downside I have discovered though is that it appears to be running a rather cut down version of Android 4.1
It is unable to communicate with my Bluetooth OBDII device, which having read through a few of the other threads on here seems to be a common issue with many of the Android Car Headunits.
The other, more annoying issue I've noticed is that when I am streaming music from my home server over 3G, it doesn't seem to support gapless playback when changing to the next track or Audio Chaining or whatever it is known as. I use exactly the same apps and set up on my LG G3 and gapless playback works fine on that.
From what I can gather, the necessary APIs to support Audio Chaining were added in to Android API Level 16 which was introduced around the time of Android 4.1 so this Headunit should support it.
I'm wondering, if the Headunit is running a rather cutdown version of 4.1, is it possible that Audio Chaining support has somehow not been added to it's supported APIs?
Is there a way I can check if this is the case? And if so, can I get them added in somehow? I'm guessing that a good place to start would be if there is a root method available for this device?
I hope it was OK to post these questions here. Please let me know if I should have posted them elsewhere.
Cheers,
Jim

Even though its an 7 inch screen it is the same as the AN21 head unit internally. So it doesnt support obdll over bluetooth. Try getting the wifi version that it works. Try the same rooting method as that head unit.
@ little off topic question
Im sorry I do not have the information on that for you but it shocked me when you said that it didn't work with your phone over bluetooth . I was thinking about buying this model and want to make sure that the Bluetooth is able to stream my music and also make phone calls from the dash !? Is that possible with this unit ?
Another question I had is about the sound quality
The watts are not listed online so does it get loud and clear or do you need an amp with this unit
Again sorry I couldn't help ( sorry for asking a bunch if random stuff )

Thank you so much for pointing me in the right direction :good:
I've had a good read through the AN21 head unit thread. I've ended up upgrading the system software to version 2.8.3 and I've also managed to root the device.
The result is now that I am able to play my music over 3G without there being any annoying gaps between each track.
As you've mentioned, it still doesn't support OBDII over bluetooth and this does turn out to be a hardware issue rather than a software issue. In fact, the software itself does clearly support OBDII over bluetooth, it's just the hardware version of my bluetooth controller that doesn't support it.

The head unit does connect to my phone over bluetooth, I never said that it didn't. I was referring to a bluetooth OBDII adapter (for reading out diagnostic information from my car's ECU) that does not work with the head unit over bluetooth.
I've not actually attempted to make or receive any calls over bluetooth, or to stream any music via Bluetooth, but it is my understanding that the head unit does support these features.
It is probably a good idea to have a proper read through the"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit [ROOTED] thread available on here in the Android Development and Hacking --> Android General section as it seems as though people have had different results with regards to sound qualities depending on which software version / MCU version they are running on their unit. For what it's worth, I've left my MCU version untouched as it looked as though it was a whole different ball game to change MCU versions as apposed to simply changing the software version.
I can't remember off the top of my head what the speaker wattage outputs are, I seem to remember something around the 45X4 mark, remember those are peak ratings. I do have an amp running a sub woofer in the boot of my car but the rest of the speakers, which are just the standard speakers that were supplied with the car, are powered directly off the head unit.
I've got to be honest and say, I don't think they go as loud as they did with my previous head unit, a Sony MEX-BT3100U, so I will probably look at amping them at some point in the future, probably after replacing them with some good quality aftermarket speakers.

Anyone know if it is possible to root the Xtrons TS702L or how to upgrade it ?

[APP][Headunit Reloaded Emulator] Running Android Auto on almost any unit.

Some of you might already be aware others maybe not, with the latest build of the "Headunit Reloaded app" you can now enjoy the Android Auto experience on almost any device. The app can be found in it's own thread, together with all the how to's and all the support: https://forum.xda-developers.com/ge...ndroid-4-1-headunit-reloaded-android-t3432348
Currently confirmed units capable to run the app:
- RK3188 based units, but only through Wifi connection
- AN-21U, xTrons, will work with USB, but only using Software decoding (occasionally that can produce some H264 decoding glitched)
-Allwinner powered devices
- Intel powered Joying units
Possibly other devices as well.
I have just updated the free trial app version to match the latest release so trial now also include all the features from the main build for those who want to try it out on their devices.
Can you tell me what this actually can do for me?

The app allows you to convert your Android powered headunit into an "Android Auto" compatible headunit, instead of buying an expensive Sony/Pioneer/Kenwood which can run Android Auto on it, you can use you existing unit to do so.

I dont understand the point - a full Android headunit can do so much more than Android auto.
Its a bit like saying "theres this great app that reduces the functionality of your device and makes it dumber".
Or have I missed something ?

Hi.
You are half way right, using "Android Auto" is way more limited than using a full blown Android, but it has some advantages as well, like for example it integrates SMS control from the headunit and data used between the phone and the headunit isn't classed as tethered data, which comes VERY hand for those who have included allowance in their phone package but not usable for tethering. Meaning you can listen to online streams (radios) on the road without tethering to the headunit. I know you can do that over A2DP as well, but most of this devices have a very cheap and bad quality A2DP receiver making listening to anything a painful act rather than an enjoyable experience.
Others will find the simplicity of the app appealing as well as the fact that it removes all the unnecessary notifications (distractions) while driving, but this like everything else related to Android Auto VS a full Android headunit is subjective.
Everybody has different needs, different preferences and so on so while some people will find Android Auto to be the best alternative possible others will say it's stupid to limit the functionality of your headunit. I tend to agree with both of them and both have valid points, I thinks it's down to individual preference.

Yes, you make some good points actually, some of which I find quite appealing. I kinda fancy some of those features on my Android headunit without running Android auto.
Just seen youre the dev, I wasnt trying to dis your project, just couldnt see the point, although I can now and yeah, its all subjective and down to personal preference.

No worries haven't considered it like that, I like to be as objective as possible, same with AutoMate, I think it's a great app and usually when I'm asked to compared it against AA I try to do it in objective way.
At the end of the day it doesn't matter which approach somebody takes until the it doesn't start with the i letter

Maybe your next project should be bringing some of the advantages of this one to people who dont want Android Auto on their Android headunit, but want some of the benefits youve pointed out, like tethering data classed as phone data and SMS control from the headunit ? Sort of a halfway house. (I m joking but kinda serious too).

Hi Emil,
I've sent yiu an email as well.
I'm in India and I just bought an android head unit. Its Allwin. When I go on the app store, I can't download the app, its not compatible.
Please tell me what to do?
@Emil Borconi , confirmed working on mtcd ha 1.63c with Hal9k_ Nougat ROM on RK3188 1GB unit over wifi! Purchasing, best of luck.
hey, it's working fine, but is it possible to change resolution to 1024x768? I can work only on 800x640, and the next one is 1280x720, which isn't working properly on my HU
