CentOS - Jun 2014 - C6.5 KDE - no more audio (yesterday it was ok)

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
00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High
Definition Audio Controller (rev 04)
Subsystem: Hewlett-Packard Company Device 1909
Flags: bus master, fast devsel, latency 0, IRQ 34
Memory at cca30000 (64-bit, non-prefetchable) [size=16K]
Capabilities: [50] Power Management version 2
Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
Capabilities: [100] Virtual Channel
Kernel driver in use: snd_hda_intel
Kernel modules: snd-hda-intel

grep snd /var/log/messages (latest boot):
Jun 4 19:45:20 Antisana kernel: snd_hda_intel 0000:00:1b.0: power state changed
by ACPI to D0

22 (level, low) -> IRQ 22


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
