Bug Description

In the terminal says:
 E: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write!
E: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_intel8x0'. Please report this issue to the ALSA developers.
E: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

I don't know how that happen. The messages appears on my terminal as background process.

I use Karmic with ubuntu kernel 2.6.30-9-generic

I have the same problem with pulseaudio on my machine using Karmic, with nvidia ck8s audio hardware. I can't get pulseaudio to play any sound consistently :-(

You need to use Karmic's kernel, 2.6.21-14.48-generic or newer, with Karmic.

Isn't this version ok?

@Juan Jesús García de Soria What problem are you having?

I won't be able to produce logs until Tuesday night, since I have no proper access to that computer right now.
What happened is that I upgraded my HTPC to 9.10, and I have no sound at all through PA. Direct alsa access works.
Sometimes I got stuttering audio from totem, if I used alsamixer to unmute all channels. The log of PA when changing volume with the tray icon said something like setting 100%, got 0%, final 0%, and would set all levels to zero in alsa. I'll get you the logs next week.
I also got the warning about the driver bug, but I'll try to confirm it again, since I was playing in desperation with the buggy_irq parameter of snd_Intel8x0 and it could have something to do with it.

Same problem here. After gnome desktop startup, the laptop freezes and needs hard reset.

Shows up in syslog every boot. Karmic fully updated w/-16 kernel. No adverse issues - other than the wasted log space.

Has anyone bothered to post this on ALSA's bug tracker? I would, but it seems as though their cert expired in July...

I haven't. I don't know where to begin with the ALSA bug traker...

https://launchpad.net/bugs/bugtrackers/alsa-mantis has a link to it. Pulseaudio claims it is an ALSA problem...wonder what ALSA will say!
