The 4.1.2 LiquidSmooth ROM was fantastic. Never once had any cd-skipping type sounds. Sounded excellent and was a flawless, bug-free ROM. Perfect if you didn't need the headphone jack, which was the only issue. BUT, I can't find that ROM download anymore. I have a nandroid and if someone bugged the hell out of me, I might be talked into uploading it. But it was a nandroid from a dirty flash so I can't guarantee it will work perfectly.

Stock ROM's skip sometimes when initially connecting audio and also when taking calls or other events occur. Otherwise they work great.

I've got great news for USB-DAC and AOSP ROM fans!!!

While USB-DAC has always worked natively on the Touch-Wiz ROM's, it has never worked on AOSP. UNTIL NOW!

Here is a quick guide:


1) Go to DanBa's list of USB-DAC's and see if your DAC is listed as compatible. If it's not listed, it may not be compatible:
http://www.head-fi.org/t/595071/andr...0#post_9083315

2) Flash dg4prez's Liquidsmooth 4.2 ROM:
http://forum.xda-developers.com/show....php?t=2080247

3) On your phone, open the "Developer Options" and enable "USB Debugging".

4) Also in Developer options, make sure to enable "ROOT" for both "APPs and ADB".

5) Flash the patch developed by Jack Norris (da MAN!).
Make sure to give ADB superuser permissions. It popped up on the phone and asked me for permission.
http://forum.xda-developers.com/show....php?t=2029728

6) Boom, you're done. Plug in that compatible USB-DAC and start listening to music!


Ufortunately,,, CM10.X and AOKP are not yet working.

Edit: Jack thinks he has figured out what's wrong with CyanogenMod and will release a patch for it soon.

Re: Great news for USB-DAC and AOSP ROM fans!!!
Do I just flash the volume control zip code or follow the PC as well?

edit: Yeah, um, just flashing volume control patch kills call audio.

Word to the wise(r than me): make sure your SD card isn't formatted as exFAT if you're coming from a TW ROM. You probably won't lose your data, but it will bork the formatting. You can restore by putting the SD card into a Windows computer SD card slot (with an adapter for most cases) and running from the command prompt:

cd c:\
chkdsk (drive letter: ) /f (without the parentheses)

I believe any AOSP-based ROM would garble the SD card each time you boot up. FAT32 is my preference...now.

Just tried CarbonROM and it did not work for me with my typical USB-DAC setup.
I posted about it on the dev thread for that ROM. Hopefully the new Carbon team can figure out what they did to make it work in Liquid and apply that to Carbon.

So how exactly do I flash jacknorris's USB audio patch?
Do I only run the .exe file?
Or do I have to flash the Nexus 7 kernels he's included as well?
I'm a bit hesitant about flashing a different device's kernel onto mine :P
Thanks!

You only run his Windows based file patch. Nothing else. No kernel or volume or any other files.

But,,, there are no longer any ROM's that support USB-DAC since LiquidROM and Xylon all updated to 4.2.2. You would have to find the 4.2.1 LiquidSmooth ROM, which I can't find anymore.

Or just stick with a Samsung based ROM as these all support USB-DAC natively, without any patching required.

Was there ever a patch for CM (CyanogenMod) created?
I've been rocking 10.1/10.2 for a bit and would love to implement in my card dock.
