Hi, thanks for your further reply. However, I don't see
"CONFIG_SND_PCM_XRUN_DEBUG" anywhere in the kernel config (both in
menuconfig or .config). Also, in order to use the snapshot I had to
disable ALSA in my kernel anyways. I did try to enable it just to see
if that option would appear somewhere but it did not. I am using
stable kernel 2.6.33 btw. I don't see how I can create
/proc/asound/card1/pcm3p/xrun_debug!
Best regards,
Derek
