Probably related: Nov 6 08:48:06 lucid pulseaudio[10496]: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! Nov 6 08:48:06 lucid pulseaudio[10496]: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA deve lopers. Nov 6 08:48:06 lucid pulseaudio[10496]: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. Forgot to add device info: 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Please use http://www.alsa-project.org/alsa-info.sh I'm observing a similar problem. Here is my alsa-info: <http://www.alsa-project.org/db/?f=2edaf27ae5afd76f0767e82d31d4515c134ef18c>. And here is my syslog output: Dec 12 02:53:20 dell pulseaudio[756]: alsa-util.c: snd_pcm_avail_delay() returned strange values: delay 0 is less than avail 16. Dec 12 02:53:20 dell pulseaudio[756]: alsa-util.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.

I have not seen this in a while (using 2.6.39-rcX). I will report back if I do. Thanks for the update. Please do. In the meantime, I will close this report. |
