I am able to build a soc driver for my hardware using the bluecore
codec driver and et1_b1_wm8731 machine code as examples.
The driver gets recognized by alsa at startup. The ssc registers are
set correctly but my original problem still remains. I can play
random noise with test/pcm_min but with test/pcm the alsa lib returns
a period_size of 0, despite the fact I set period_time to 100000.
I start to suspect that I have a problem with alsa lib. How did you
cross compile alsa lib för the at91?
