Hello Everyone! This is a movement/project to get MHL going on CM10 ROMs. I have started tearing into it as some of you may have seen on some other threads, but I am just a noob
I would love some help on this. I am not good with programming or working with source so i have posted my changes on pastebin. Reason for that is so that you guys (and gals) can help out! If you know what you're doing and can build with some changes you make yourself, please go ahead and do so, but keep me informed. If you are not as savvy with this stuff like me, you can still help by searching through the code and trying to see what is missing or out of place! Thank you to all that help out. Post any news or questions here!

Attached log files from attempting MHL use on AOSP and actually doing it on Sense 3.6.
Big Thank you to SirGatez

Sense 3.6 only. The Sense 4.x builds do not support MHL.
To the OP, thank you guys so much for attempting to make this work. You guys keep breathing life into this device. Your work is VERY appreciated!

Question. I don't have CM10 installed right now but you guys have tried adding "ro.hdmi.enable=true" to the build.prop? Worth a try.

I thought thus was used for HDMI only and not the mhl connector.
Cm10 trys to output video to USB when connected to the mhl device. It just doesn't know how. Someone posted a logcat and it shows its passing the information to com.android.athome.mediaroute.provider
But errors right there. Unless I'm looking at the wrong error. But I need to look at it some more. Couldn't do much at work today. :/

I've been reading a lot and CM10 seems like it has problems with MHL anyways. You say it tries to push it through USB but just doesn't know how to. That would be kernel issue would it not?
I will be able to start testing when I get my MHL adapter back tomorrow. I got a lot of free time to test since I'm done updating recoveries for now
EDIT: I reading more and saw where one guy somehow changed his refresh rate to [email protected] inside of the kernel. So is it somewhere in there most likely???
im also good to test. might be sending the phone in though so sooner rather than later would be good. It seems that everything starts with the ActivityManager file... i could be wrong though.

Kernel is built with HTC source. I would think it would carry over but I'm no way a kernel dev. The jar file posted in the other thread might be needed but I haven't had time to look at it yet. As it sits now the phone doesn't know how to pass the information from the screen to the USB mhl to the TV. I think the reason why screen says source and just black is because its getting some sort of output.

I think the real issue is as I discussed else where (where I posted the logs in CounterShrike) and the issue is that the kernel has everything it needs to utilize MHL hardware and the HDMI out driver is functioning (but separate from the actual media pipeline. The pipeline portion that MHL require to function (the middleman that takes the graphics, sound and sends them to MHL hardware) does not seem to be in our sources (not the kernel, but the libraries) because it is proprietary. I am going to experiment with trying to hack the display middleman into AOSP and see if it works, with any luck it will be drop in and won't require anything HTC specific.
In Stock once the MHL cable is connected an HDMI broadcast is sent and picked up by the DisplayListener which responds by handshaking and configuring the MHL/HDMI output of the device before handing off to the AudioListener which does the same. AOSP is not performing any of this short of identifying the MHL cable is connected and rotating the home screen for display (it also appears any portrait app besides the home screen stays in portrait mode regardless of MHL cable connected)
This is an issue affecting many MHL capable devices, NOT just the Rezound. I have read MHL does work on some AOSP devices but I have not been able to locate any source to specific roms capable of it (which could help us). I think our best bet is a hack until we can get/find proper source.
Once we can get the DisplayListener and AudioListener to handshake with MHL/HDMI hardware like Stock we can identify what else we may need to fix if we are still without picture and or audio.

Hmm..That is true. Should be taken from original source unless Chad has modified a file which I doubt that is the case.
EDIT: Or what he said above This guy has his MHL fix in his kernel at https://github.com/ZenArcade/Infusion-GB-Z/commit/e70be75f5e709ef17df9dd2705bee1b810e0a2b6
waiting for a reply back from meetmhl on exactly what files are used in the api. Hopefully it's something as simple as missing a lib.

I believe this rom has working MHL. https://github.com/rascarlo/platfor...jb-ras-mr1/core/java/android/hardware/display
Very good work cslingerland and Flyhalf205. Could one of our AOSP devs check this code out and see if compiling it into the ROM resolves our MHL problems? I do not currently have a development environment setup Someone would likely beat me to having a compiled library ready. I would have to D/L some source first as I haven't done any kernel dev work since Gingerbread. Thanks!
FYI, HDMI/MHL has nothing to do with USB, they just share a connector (it can do USB or MHL, not both).

anyway, can we get a mod to change the maker of my first post to rigy?
Try looking at the Archos gen8 kernel sources. They use OMAP36XX and a similar PMIC if not the same one. I don't think the NC has a charge pump and don't think you can rely on ID to detect an otg cable.
Good luck!

Great Idea...

But I've got plenty of devices I can test with if you get to a point that would help...

Evergreen has done a good bit of work on this already. He will be back next week.
I've also been actively working on this.
I have gotten the musb into a_idle in the past and also just echoing host into mode seems to start some of the transition. I'd pin seems to be a lost cause and I gave up on. It already.

TPS65921
It looks like rigy73 has already uncovered most all of what i've been able to pull together as well as some extra testing information. So glad everyone who has been looking at / working on this is coming together to share.
Here is a link (if needed) to more documents regarding TPS65921:
http://focus.ti.com/docs/prod/folders/print/tps65921.html
It contains the datasheet, and under technical documents has register manual.
This. I mean with this no more worrying about bluetooth keyboards! And hopefully we could even get crazy things like ddr pads working ;p. Talk about the ultimate game system on the go.
Two kernel patches added.
Have you contacted anyone on our CM7 team to include it in the kernels (fattire, dalingrin, etc)?
I haven't tested it personally, nor do i have any proof that it is actually working, it can be included once we know that there are no problems in the code.
Really interested in seeing this happen =D.

That's what i figured too, who else would want to make nook more awesome.
And has anyone been able to get this working?
THANK YOU!
Sorry for the screaming, but this is amazing. I was just looking into this this morning because, RcketScientist is working on a camera raw patch. This is the last thing my Nook needs. I am not great at compiling, but I will help when things get a bit more stable. Is this going to be able to patch the stock kernel? Will it be flashable? or incorporated into a new build? Sorry if I am jumping the gun.

I presume the usb port of the NT is unusable until a kernel level root is developed. If someone would confirm for the hell of it, please do! (I grabbed a couple usb to micro-usb converters - but, no luck...)
I didn't research the usability until after I tried using the usb port! I figured it would be enabled... why not allow a keyboard, etc.? Anyway, that explains why I couldn't find out the 'port type' in the official specs (micro usb).
Read some stuff on the Nook Color - and I believe the usb is available for it when rooted.

Yeah - I guess as a USB host is the terminology I needed. I'm rooted - so, the Nook works fine as a device on my PC!
I just want to run devices from the Nook itself - particularly keyboard and game controllers (ps3).
It never occurred to me that it wouldn't function 'out of the box.' The only reason I can see to deny it is either battery drain or to guard against hack attempt. Pretty lame really!

Do you think it might be possible to replace elements using root to enable it?
Barring that, in one dev thread or another, I vaguely remember reference to a particular way of bypassing the bootloader lock, that if it worked would allow us to use custom ROMs but we'd be stuck with the B&N kernel. Does that sound familiar? What I'm really asking to anyone who might feel they know, is what are the odds the devs might crack USB host even if they can't get past the bootloader lockout?
Thanks to anyone with information.
Once this is enabled we wont just be able to use a keyboard, but also use it to browse your camera pictures, hard drives, etc

Cyanogenmod has USB host enabled. You could ask a cm dev how it is done. Dalingrin works on the Nook Color port, he may be able to tell you.

Ok i havent gotten my samsung galaxy player 5.0 yet but i am working on it i ran across these 2 amazing accessories. And i was wondering has anyone else tried this on there device. Let me know any info you may have
HDMI HHL Adapter
http://www.amazon.com/Menotek-Adapt...Sensation/dp/B005F9W6DU/ref=pd_bxgy_cps_img_b
OTG Cable
http://www.amazon.com/T-Flash-Adapter-Samsung-GT-i9100-GT-N7000/dp/B005FUNYSA/ref=pd_cp_e_1
As for the HDMI,
The Samsung galaxy player, dose not support tv out
No OTG support (yet). They recently ported it to the galaxy s, we might be able to get it to work at least on the 4.0, witch is pretty much identical from what I have seen. So far I have confirmed their partitions are mounted identically, they have the same CPU, and I think they might even have the same motherboard (both of them have "ro.board.platform=s5pc110" in build.prop, not sure if that is the MB or not). The 5.0 is a totally different story though...
OP, you should go for the korean version if you want the HDMI output.
This version also supports 1080p (the device is also in english), has 16 or 32gb, and I found something very amusing : the korean version is made in Korea, whereas all the other versions are made in China. I guess koreans only buy korean products, haha! But I couldn't tell if it's any better...
MHL is definitely not present in the 5.0 - I tried the adapter that came with my Infuse.
There's a chance it might support analog TVout via the headphone jack, but this is unknown and no one has tried it yet.
Sent from my GT-P7510 using Tapatalk
Hey entropy512, would you be willing to edit the settings.apk for the 4.0 U.S. version if I sent it to you, then someone with the right cable could see if the tvout works?
I have a TV out cable from my ipod 5g, if someone needs testing, i'm game
When I plug the cable into my headphone port, no picture shows up, however the audio dose not switch to headphones, it keeps playing through the speakers, so that must mean something...

Yep, it means that your headphone jack detector works.
Dang, I'm almost sure this has video out, at least the 4.0 since I think it even has the same MB as the gt-i9000! I sure wish I could smai edit the settings.apk so that the option would show up, but I've been looking for a good guide on doing so and have yet to find one. I havn't had time to just learn smali as I have school, so unless there is someone out there with a 4.0 (possibly 5.0 has TV out as well, but less likely) that knows how to smali edit, we're stuck.
If you want tvout settings to appear then all you should need to do is get a settings.apk from a gt-i9000 and load it. Make sure it is the same framework as the one that you are running eg. 2.3.5. The setting will show up but I have found that just having the setting there does nothing if the functionality is not there...
Let me know how it goes...
Sent from my YP-G70 using XDA App
Well, I asked for the apk two days ago on the gt-i9000 forum but no one ever responded. Guess I'll go bump the thread! I guess those galaxy s owners are to busy to help a poor galaxy player owner, lol!
FYI, You don't need to ask, all you need to do is download a full rom for gt-i9000 and pull the settings.apk out.
You can use "kitchen" to do this if it's an odin flash, if it's a CWM zip then just open this zip and extract it out...
Ya, I thought of that, my internet is really slow though, guess I'll start it and it will be done by tonight.
Well, I tried the settings.apk, but it fc when I select display, or any other menu. Any suggestions? I guess the real way to do it would be to smali edit the original, but I have no idea how to do so.
Well, I have a 5.0 and not a 4.0 and I'm using 2.3.6. In the 5.0, settings for tvout are not there. It's just not in the code. If I were you, I would use adb logcat to get the exception info to find out why the settings.apk is fc and go from there....
Eh, I think I might call it quits for now. I've got a busy month, so if someone wants to pick up where I left off, here is the apk someone gave me.
forum.xda-developers.com/showthread.php?p=22106185#post22106185
Why doesn't OTG work on the galaxy players? I thought it was standard in all android devices?
I think this player not support TV out?
There is a small chance it supports TV out via the 3.5mm jack. Someone needs to test it with a correct cable first, to confirm or deny.

hi guys,
after abit of help. i bought a hdmi adaptor, from amazon this one http://www.amazon.co.uk/gp/product/B007K8NNOA/ref=oh_details_o02_s00_i00
so that i would be able to play content from my phone straight through to my tv. I also bought a new hdmi lead and i connected using the phone charger and lead that came with the phone.
When i plug it all together it shows on the phone that hdmi out is connected and i can display video or photos on the external device. But no matter what i do i cannot get a picture to display on the tv.
Am i doing something wrong? Or does it never work? I tried rebooting the phone i tested the hdmi lead to make sure it works. Is there another option on the phone i need to select to i need to use a different app?
Any advice would be greatly appreciated.
Are you on the stock rom/kernel? I can't say I use this feature as much as I thought I would, but I have noticed some kernels break this feature (though I can't say which ones anymore - been a while) and I've seen some roms break this as well. I don't know if this was a placebo or what, but I also noticed that it broke for me after removing some of Sprint's or HTC's bloatware... I think it was the transfer app, but it doesn't make much sense to me why.
I'd try it on a full stock rom/kernel first to make sure it's not software related. Then try it on multiple TVs. I actually had an experience once where it wouldn't display on my TV, but worked fine on my HDMI enabled pc monitor - same symptoms you're describing. Tried different kernel, all was better. But I've also read about people just having a bad mhl adapter or bad hdmi cable too.
As above it needs to be supported by rom and kernal. Try a stock configuration and see what happens. If that fails it might be a faulty adaptor, these cheap ones are known to fail easily.
i appreciate your guys help. i am on stock rom/kernal. my tv is pretty new. The phone is showing as having a hdmi connection so wasn't sure if it could still be the adaptor? i will try it on another tv at the weekend. if it still doesn't work maybe send the adaptor back?
so it should display whilst playing a film through the stock video player? i dont need to use a special programme or anything else?
It automatically displays whatever is on the phone's screen. No need for anything special beyond plugging it in. It could still be a faulty adapter even though the phone shows hdmi.
Another idea might be to double check your tv out settings on the phone. Make sure those are correct.

You have to have it plugged into the wall outlet as well. Just a thought

still thanks for all the help.
Hey, I've been through the forums searching out whether the i9100 has the capability to run its audio through a usb dac and have only come up with old and dead threads. This http://blog.jdslabs.com/?p=838 is saying that to utilize at lease their dacs you only have to either be compatible with usbaudioplayerpro or have a cyanogenmod rom (i'm guessing CM10/11). I've checked the compatibility list for the usbaudioplayer (http://www.extreamsd.com/USBAudioRecorderPRO/) and the i9100 isn't officially compatible because it has "No USB host mode" at term I think is synonymous with otg, and I've used an otg checker and my current setup (i9100 with http://forum.xda-developers.com/gal...m-gt-i9100-resurrection-remix-v4-0-7-t1436854) has that capability. On top of this the resurrection remix 4.4.2 rom is based on CM11 and so that makes me think that it will have the usbaudio problem solved anyway. I hope that I haven't missed anything significant, and for those wondering, the reason I haven't posted this in the rr thread is that I need ten posts to post there. Hopefully someone can confirm that this is now possible so that I, and others interested can go about buying usb dacs to bypass the shoddy yamaha internal dac.
tldr; is it now possible to run a usb dac on the i9100 using the new kitkat roms (specifically http://forum.xda-developers.com/gal...m-gt-i9100-resurrection-remix-v4-0-7-t1436854).
Thanks,
Luke
TL;DR = no.

I've seen that you have always been on the answer end of these threads, hopefully you can tell me why this really is and what steve kondik's work has done for the situation as I've read that he solved the problem for CM (an idea backed up by the original link i posted). Why has his contribution made the difference on other models but not this one? So it's a hardware issue or? Sorry if you just end up repeating yourself but it's not quite making sense.
Thanks,
Luke
I've been on the answer ends on a lot of these threads because for the two yrs I used my S2 (I don't anymore), I was very keen to have USB DAC functionality for myself if it was possible. Yes, everyone is aware of what he's been able to do, but it isn't possible with this device due to hardware limitations.
Trust me, if it was possible, it would have been done by now, as you know you're not exactly the first person who would like this to work.
Edit - It hasn't solved the problem for CM period, it's solved the problem for a number of devices. If you don't believe me, flash CM & see if you can get it to work.
Sorry for the thread resurrection... I happend to browse across the following, which looks promising:
- Galaxy S2 DIY Car Dock with USB audio output (https://www.youtube.com/watch?v=skgEKS4uzWA)
- [HOWTO] Enable the car dock external audio without Samsung's Home apps by TheBeano (http://forum.xda-developers.com/showthread.php?t=980937)
- Fun with resistors (home/car dock mode + more) by TheBeano (http://forum.xda-developers.com/showthread.php?t=820275)
I am also kinda interested in this.
So far it seems that my headset is being detected by my s2 running pac rom.
There is still no sound output.
I would say it is because the lack of usb audio drivers in our devices.
All that is needed is to compile the snd_usb_audio.ko module and load it.
From there on, I assume android can handle it well enough.
Otherwise we can use alsa directly.
Edit: After loading the module, sound works (from chroot) but I don't know how to tell android to output to the headset.

Hi ruleh, can you try this trial app 'USB Audio Player PRO' to test if it works? https://play.google.com/store/apps/details?id=com.extreamsd.usbaudioplayerpro
You can find the trial link in the app description section.
Do let us know your findings.

I will look at this at some point after I get my kernel sorted out.
(probably this week)
--- edit ---
after a few more staring at the item (as item gallery does not have better view perspectives), i could be wrong... ha. i'll update back once i have more details ya.

i found this cable, "USB 2.0 Adapter Splitter to micro usb 5pin + Car Aux Stereo Jack audio 3.5mm" - http://www.wish.com/geek/m/c/552f5808563a980bffe08ae8, which allow phone to go into "car mode"... i have yet to try, but i believe with this, you no need to diy your own as mentioned in my previous post; and it seems that you only need to rewire the 3.5mm audio jack to the usb male connector...?
ha. my two cents.
