Maybe some amplifier is not enabled? On iPAQ h1940 and rx1950 you need to toggle gpio pin to hear something from internal speaker (not sure if that pin disables headphones).
When I change volume of Analog Mixer the noise in headphones is getting stronger or weaker so GPIOs in my opinion are set up correctly.
I'll enable debug messages on i2s bus and see if there is sth sent to codec. Maybe alsa is sending music packets to /dev/null.
I will also want to see what debugfs files should contain when audio works. Could you send me few examples or point me to address with them?
