Replace card0 and pcm0p with right identifiers (look to 'aplay > -l' for right numbers). > > More info: http://www.alsa-project.org/main/index.php/XRUN_Debug 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!
