Hi,
I've got an HP ZBook with C6.5 and KDE. Yesterday I was able to play music,
today I can't get any sound out of my pc.
lspci -v

Elsewhere in messages I find a occurences of
Jun 3 17:50:56 Antisana pulseaudio[3454]: alsa-sink.c: Waarschijnlijk is dit
een fout in het ALSA-stuurprogramma ‘snd_hda_intel’. Meld dit probleem
alstublieft aan de ALSA-ontwikkelaars.
Jun 3 17:50:56 Antisana pulseaudio[3454]: alsa-sink.c: We werden gewekt met
POLLOUT ingesteld -- echter een opvolgende snd_pcm_avail() gaf 0 terug of een
andere waarde < min_avail.
(but the sound worked at that moment)
I tried with alsmixer, alsunmute and PCM and Master are unmuted and maxed.
Any ideas?
Thanks

Now wait a minute, after a reboot sounds works again... feels like I'm back to
standard Windows troubleshooting :-)
Anyway solved for now, sorry for the noise
Greetings
Patrick
