[Bug 464442] Re: alsa-util.c: snd_pcm_delay() returned a value that is exceptionally large: -4496252 bytes (-25488 ms).

[dermoth]

I have similar problems after upgrading from Hardy to Lucid. Sound
always stops after playing movies or using other applications for a few
seconds/minutes regardless of the application used (I broke the sound
with mplayer, vlc, totem and even the Multimedia System Selector app
sound test).

Once broken, I can get sound back if I restart pulseaudio with:
$ pulseaudio --kill; pulseaudio --start

Sound always worked well in Hardy except for some glitches regarding
sound control.

Each time sound breaks, I see this in syslog:

Apr 27 02:55:15 dermoth pulseaudio[32250]: alsa-util.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.

As for the hardware I run on, you can see attachments for this bug which I reported today...

dmesg doesn't show anything new besides these two pulseaudio segfaults which seems to have occurred during two of the numerous times I broke the sound while testing:
