Try 'echo 101 > /proc/asound/card0/pcm0p/xrun_debug' and send dmesg output to check if the ring buffer pointer in the hda-intel driver does not return wrong values. Replace card0 and pcm0p with right identifiers (look to 'aplay -l' for right numbers).

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!

All these parameters should be set: CONFIG_SND_PCM_XRUN_DEBUG, CONFIG_SND_VERBOSE_PROCFS, CONFIG_SND_DEBUG . I updated wiki.
