oops, the patch was wrong.  could you try this one (and remove
/etc/asound.state before starting ALSA?)

also, if it still doesn't work, try to change the ADC VRA.
for example, run "arecord -fS16_LE -r44100 foo.wav" once before
playing 44100 samples.

also, to make sure that it's a hardware problem, please avoid mono
samples but use 16bit stereo samples only.
