which device are you using ? ( pulseaudio , dmix or default device defined in /usr/share/alsa/cards/*.conf )

Hi,
I have the same kind of problem. I try to capture PCM stream thanks to areacord : # arecord -c 1 -t wav -f S16_LE -r 8000 -d 10 input.wav
30 seconds later I have the folowing message : # arecord: pcm_read:1629: read error: Input/output error
I can observe the PCM stream on an oscilloscope but no interrupt are catched by the system (AIC ss0 counter remains at zero ) : # cat /proc/interrupts CPU0 1: 275059 AIC at91_tick, rtc0, ttyS0 7: 179 AIC ttyS2 9: 11 AIC mmc0 13: 0 AIC atmel_spi.1 14: 0 AIC ssc0 82: 1 GPIO alerte 107: 9464 GPIO eth0
Any idea?
