[Nexus 7 Android Development] andrew9292:
As promised, here are the logs! :D

So here's my DAC experience (warn: might vary very differently from person to person)

MultiRom Jan 04

Primary ROM: Purity Jan 05 / Franco r77 / ART

Secondary ROM: Zeljko Jan 08 / test kernel / ART

Test method:

1. Wipe davlik & cache on secondary ROM

2. Install kernel to be tested

3. Reboot into ROM, let it do that dalvik/art optimization, wait 5 minutes after to be safe.

4. Reboot again into ROM with DAC plugged in (direct-otg ; NOT using OTG-Y)

5. Test playback with Youtube app to see if on-boot works.

6. Unplug-replug DAC to see if hotplugging works.

7. Get dmesg

*ROM = Zeljko Jan08

*DAC= PCM2704

Current results:

Kangaroo 1.2 > DAC hotplug works ; no output if plugged in on boot

Oxydo v15 SELINUX > DAC no output

Leankernel 3.1 > DAC hotplug works ; DAC on boot works

Reference lines to DAC, not really sure what's what but tried my best (find '2704' / 'usb audio dac' in text editor):
