Also, after I do:
echo 1 > /proc/asound/card0/pcm0p/xrun_debug
1 is not enough

you need 11 to find out whether hardware pointer are correct on period update
and how often lost interrupt occur compared with period update ?
# Enable basic debugging and dump stack, check hardware pointer on the period
update
# Usefull to just see, if PCM stream is stopped for a reason (usually wrong
audio process timing from scheduler)
# And to check the values from driver
echo 11 > /proc/asound/card0/pcm0p/xrun_debu</pre>
