ALSA/pulseaudio issue?

[Ulrich Windl]

Shortly after starting Qubes OS 4.1 I noticed this message in syslog:

Dec 08 20:10:48 dom0 qrexec-policy-daemon[4745]: qrexec: qubes.GetDate+:
sys-firewall -> @default: allowed to dom0
Dec 08 20:10:48 dom0 pulseaudio[7749]: ALSA woke us up to write new data
to the device, but there was actually nothing to write.
Dec 08 20:10:48 dom0 pulseaudio[7749]: Most likely this is a bug in the
ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA
developers.
Dec 08 20:10:48 dom0 pulseaudio[7749]: We were woken up with POLLOUT set
-- however a subsequent snd_pcm_avail() returned 0 or another value <
min_avail.
Dec 08 20:10:48 dom0 qrexec-policy-daemon[4745]: qrexec:
qubes.WindowIconUpdater+: sys-firewall -> @adminvm: allowed to dom0

Is that a known bug?
