[Bug 637947] Re: no sound devices on current ES2.0 boards

[Bryan Wu]

I got one more audio fixing patch from Sebjan and pushed all the audio patches here:
http://kernel.ubuntu.com/git?p=roc/ubuntu-maverick.git;a=shortlog;h=refs/heads/ti-omap4

And a audio fixing kernel was built for testing:
http://people.canonical.com/~roc/kernel/audio/

After installing the audio kernel on my ES2.0 8 layers board, I did following testing:
 - cp SDP4430.conf from Berco to /usr/share/alsa/cards/SDP4430.conf
 - aplay: http://pastebin.ubuntu.com/503799/
 - pulseaudio: I followed David Henningsson's wiki: https://wiki.ubuntu.com/PulseAudio/Log. PA fails to run, here is the log: http://pastebin.ubuntu.com/503801/
 - run alsamixer -D hw:0 to turn on earphone and headset
 - run speaker-test -D plughw:0,9 -t sine -c 2, I can here sound from my earphone.

So far, I think kernel's ASoC driver works, maybe some audio system
configuration issue blocks us.
