[alsa-devel] snd_hda_intel error

[Jack Byer]

I found this message in my system logs:

Dec 04 07:25:52 [pulseaudio] alsa-util.c: snd_pcm_avail_delay()
returned strange values: delay 0 is less than avail 8.
Dec 04 07:25:52 [pulseaudio] alsa-util.c: Most likely this is a bug in
the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA
developers.
