But when I want to record a pcm stream I have this error: # arecord -v -c 1 -t wav -f S16_LE -r 8000 -d 10 input.wav arecord: pcm_read:1629: read error: Input/output error
[With an AT91 in slave mode...]
and actually no interrupt occur and I wonder why...
Can you see clocks on the audio interface? Have you checked that the pins on the processor are configured to route the signals to the correct IP block?
