I'm seeing something similar here, in a QEMU virtual machine started
with -device intel-hda -device hda-duplex. The only difference with the
logs reported by Tobias above is the alsa driver in second line:

data to the device, but there was actually nothing to write.
Nov 30 03:53:00 debian pulseaudio[600]: Most likely this is a bug in the
ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA
developers.

set -- however a subsequent snd_pcm_avail() returned 0 or another value
< min_avail.
