Bug report: https://bugzilla.redhat.com/show_bug.cgi?id=498858
To reproduce, pause a video in mplayer and then hit play:
ALSA sound/core/pcm_lib.c:263: hda_codec: hw_ptr skipping! [Q] (pos=11263, delta=17400, period=1024, jdelta=21/362/0)
Does the patch fix the problem?
This patch does not look as a proper fix.
Hm, at which point? It just skips the first unreliable jiffies check. At least, it's interesting whether it works around the problem.
thanks,

Takashi:
I have submitted https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4523 in regards to this problem. I can recreated the xrun messages 100% of the time and the routine in question never recovers. With a workaround suggested by Jaroslav, the xruns go away, but the calling process ramps up to 100% CPU utilization and unless you are on a dual or quad core machine there is quite a lockup. I revert to the 1.0.19 pcmlib.c in the 1.0.20 driver and I see neither problem. Thanks for all of your help Jaroslav. If there is any way that I can help debug this problem, please let me know.
Best Regards,
