Bug#717970: pulseaudio: alsa-sink alsa-sink.c ALSA (POLLINVAL) woke us, but nothing to write (Error in snd_usb_audio)

[pheanex]

Package: pulseaudio
Version: 2.0-6.1
Severity: normal

Extract from syslog:
pulseaudio[4186]: [alsa-sink] alsa-sink.c: ALSA weckte uns auf, um neue Daten
auf das Gerät zu schreiben, doch es gab nichts zum Schreiben!
pulseaudio[4186]: [alsa-sink] alsa-sink.c: Dies ist höchstwahrscheinlich ein
Fehler im ALSA-Treiber 'snd_usb_audio'. Bitte melden Sie diesen Fehler den
ALSA-Entwicklern.
pulseaudio[4186]: [alsa-sink] alsa-sink.c: Wir wurden durch das POLLOUT-Set
geweckt, allerdings lieferte ein anschliessender snd_pcm_avail() den Wert 0
oder einen anderen Wert < min_avail.

And what happens after this? I fail to see the problem here (other than
a noisy syslog). Does sound still work?

This could be related. Could you please run this:

pulseaudio -k ; LANG=C LC_ALL=C LANGUAGE=C pulseaudio -vvvv
--log-target=file:/tmp/pa.log

And then submit that file? It will give us a full verbose log, and in english ;)

Also, what version of pulseaudio and linux kernel do you have
currently installed?

Lets try to make it work better ;)

Unfortunately, the pulseaudio daemon is already running. Please see if
there are any pulseaudio processes by a user that is not your own:

ps -fea | grep pulseaudio

If you do not have any, please retry the earlier command a few times
until the daemon manages to start (the problem is that pulseaudio
autorestarts, so the second command needs to win the race against the
autostart, which it can take a few tries to get).

OK, this is a wheezy system then?

I don't see the error in the log.

I'm reassigning against vlc, perhaps it is a problem in vlc.

VLC maintainers, please reassign back if you find it is a problem with
pulseaudio.

Sorry for long delay. Is this still an issue with vlc 2.2.0~rc2-1? Could you
please also attach the vlc -vvv output when the issue happens.

It seems to be fixed in 2.2.0-rc1 Weatherwax (revision
2.2.0-pre4-97-g8a35de1), or at least it didn't happen any more =>
consider it fixed now?
