I have the same problem on Android on Nokia N800. I have made a link of /dev/eac on /dev/dsptask/pcm1 and so using a mp3 decoder little noise appear on system speaker but nothing else. Instead after created /dev/eac with 10,63 no sound.

Have you some suggestion?

Hey, all

I'm trying to configure sound on my android board. After long searching...nothing. The mixer of audio codec is set up with simple mixer application before running android. When I created node /dev/eac with numbers 14,3 (the same as /dev/dsp) noise appear in system speaker, so android surely calls /dev/eac. I'm playing MP3 audio file with prepared by me application (checked on emulator) and there is only some digital noise on audio output.

ALSA drivers are enabled on my kernel. Enyone knows something more about Android sound...?

Here is something interesting about android sound:
