As the other thread is set as [solved], I made a new one, as it is not solved for me...
To check what happens I got me the left/right test track from binkster.net
And it definitely puts all audio on the left channel, the left channel data a lot quieter than the right channel data, but everything together onto the left front channel.
I guess the receivers show 5.1 because the hdmi data is indeed a 5.1 channel format, just without any sound on most of its channels. And I believe the reason it works on some TVs, is that they just detect a mono signal and put it on all speakers, or they only have one speaker in the first place.
As the audio and hdmi HW is inside the Tegra 3 SoC and the same test file plays fine on the same hdmi setup with my Tegra 2 LG P990 phone with microHDMI out, I doubt this is a hardware problem, but that Asus somehow uses the mixed up mono signal from its own single speaker as output over hdmi as well...
But maybe I am wrong, is there anyone who actually gets this left/right test to play "left" on the left speaker and "right" on the right speaker ?
I marked my thread as "solved" because I found (notes in the thread) that the prime and cable "work". But they don't "work correctly" for all connected displays. Some didn't work at all, some didn't have correct audio (as you have). Some worked perfectly. Maybe "solved" is not correct. "Understood" would be better.
My TV doesn't have correct audio either, but at least I know where the problem is. And I could buy a new TV if I had the $$.
I have opened a case with ASUS and hope to get some more info from them later this week after the holidays are well behind us.
I suggest you open a case with ASUS as well to motivate them.
Good luck.
Is there a way to look into the audio configuration? Is it alsa? Maybe they mix channels to mono there?
I poked around with various market apps and couldnt find any info.
I haven't had time to look thru the kernel code. Hopefully ASUS will post an update.
NOTE: the audio is fine with some devices. So it doesn't appear (as I first wondered) that its a mixer problem.

I opened a case already, but I think it will not really help Asus much, actually more the opposite and confuses them rather, as I mixed up right with left in my report to them
Can you download the left/right test file from binkster.net by any chance and test it on those TVs where you thought it worked and listen closely if the two words actually come from the correct speakers or just from the middle of the TV ?
In the audio track, the word "left" is spoken only on the left speaker and the word "right" on the right speaker
Thanks !

I haven't found any audio options except volume. If there are any, I would be thankful if someone can point me to the right menu to access them.
Today's update fixed my audio problems. I hadn't previously checked with my Samsung c8000 3d led TV, but I was having left channel and center only audio from my Onkyo tx-nr 809 avr. Now I'm hearing audio from all channels both from my receiver and TV.

Rats. You had my hopes up that todays update would fix my hdmi audio problems.
I just confirmed I have the latest build (8.8.3.33) and I still only get audio out of the left front speaker on my Sony TV over HDMI. Glad it helped some people.

Yes, I just wanted to make sure the TVs did not "intelligently" spread out the mono signal onto both speakers, which could be verified by the test file.

peare,
Does the Onkyo controller app from the market work on the prime?
I am on 8.3.3.33 now and STILL got the mono sound problem.
I connect my TF Prime with my Onkyo TX-NR509 receiver, which is quite state of the art. Besides, I am using a very professional HDMI cable with 1.4 standard.
Sound is only playing on the left and the center channel.
Anybody heard something from ASUS regarding this issue?

Not for me. Audio was working perfectly until I installed ICS now I don't get ANY sound over HDMI.
Has the output type changed or something? Perhaps my amp's settings need to be changed after the ICS update. There isn't a problem with the cable as the same file played ok from my computer using the same HDMI cable and input. A small chance the micro adapter is broken I suppose, but can't really test that as have no other input sources.

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!

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.

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 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.

Why can't it be done for android? This app is really cool.
Sent from my SGH-T959 using XDA App
It should be possible...
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!

How about USB OTG connected to a Rocksmith USB connection?...
Sent from my SPH-D710 using xda premium
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"!

Hi, as the audio recording with the built in mic is very poor, i wonder if there is some kind of USB dock with audio "line-in" capability!?
I think i have seen that for the "bitten fruit" pad...
Does anyone know how to get a good audio recording quality?
My target is to record my guitar (electric and acoustic) while practising with great guitar apps on the tablet.
This would completely round off the guitar practising experience.

Tascam works wonders if you use it with headphones directly connected to it and no modeling.
We, Android users, are screwed when using real time or low latency modeling/amp simulation cause Android audio drivers are quite bad right now.
The latency of what gets in the phone and what you hear is an abomination hehe, it makes impossible to use an app to simulate a pedal or add add an affect for example. The issue relies in the Audio driver used by Android.
As far as i know l, it has been in the Android bug tracker for like 3 years now and it hasn't been fixed. You can search for Android issue 3434.
That's why for example AmpliTube has not released any app for Android

Sorry if this topic has been done to death, but do any of the ICS versions for the G-Tablet have working HDMI audio, through the dock or otherwise? It's the one feature remaining that I'd really like to have for TV viewing (I suppose I can run analog audio-out to my receiver), This is not meant as a knock against the developers who are working hard to keep the G-Tablet viable, but could you give us an ETA for HDMI audio, or should I start looking at other options? Thanks.

Has anyone tried this device with Miracast/Samsung Link (screen mirroring)? Using a Netgear PTV3000 Push2TV with the Galaxy Mega 6.3 (AT&T) the audio quality is extremely poor without any definition, sounding like mono with no bass or treble extension. I used a Note3 (AT&T) with the same Netgear PTV3000 and it sounded great. Both devices had identical and mostly excellent video quality via the PTV3000 (as long as no other programs are running or you aren't multitasking on the device). The audio/video was tested on the Mega and the Note3 using MX player, Pandora and the Android stock music (MP3) players.
I read on this forum the Mega stock video player does not support AC3 or DTS encoding of which I didn't test but I don't know if that factors in or if something else is going on. The Mega is running Android 4.2.2 stock ROM and rooted. The Note3 is running Android 4.3 stock ROM and also rooted. The PTV3000 is now updated to the latest firmware 2.4.26 and I have manually reset the device using the reset button on the back as well. Also, using a genuine Samsung MHL 2.0 (white) HDMI adapter both devices play audio and video without any sound or video quality issues.
Any help or suggestions would be appreciated. I'm sure I left out some important details.
Sorry to hear you have this trouble. First off please make sure that you turn off any audio effects on the Mega. Secondly I am sorry to say, the decoding chip on the Mega is maybe not powerful enough for what you're trying to do. Thirdly, Maybe you can try a different player. I have had good results with the Archos video player on the Mega. Good luck!

What audio effects that you mention could be enabled/disabled? Where would they be located to change? I have gone through the device and only found the option to change the HDMI audio between stereo and 5.1. The solution you mentioned could help with playing audio in videos but it persists in Pandora streaming radio along with the stock music player too. I was thinking the same thing regarding the device itself after researching and thinking about the embedded hardware, there may be a limitation to what the device can do though I would expect it to be in the video encoding performance over Miracast and not the audio quality. I will try it out though and see how it works. Thanks.
I was referring to the system setting. Go into settings then accessibility. Tab sound balance and make sure it's in the middle. Then also uncheck mono audio.

You might not believe this but after reading a suggestion on another message board plugging in headphones and then unplugging them triggers high quality audio over Miracast on the Mega. It leads me to believe this is a ROM issue. Any thoughts?

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.

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 )

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.
