Hi George,

Here was the relevant stuff from your error log:
> Mar 22 09:03:20 ltsp24 pulseaudio[2663]: alsa-util.c: snd_pcm_delay() returned a value that is exceptionally large: -655328 bytes (-3715 ms).
> Mar 22 09:03:20 ltsp24 pulseaudio[2663]: alsa-util.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.

And from https://bugzilla.redhat.com/show_bug.cgi?id=506075 :
> I can't listen to music (or watch video or Flash)
> more than a couple of minutes, before pulseaudio reports the snd_pcm_avail()/

Or this:
https://bugzilla.redhat.com/show_bug.cgi?id=485734
> intel-hda: snd_pcm_avail() overflows

This could be the problem you're seeing, an Intel ALSA driver bug that
someone reported in Fedora 11 2.6.29 kernels, but apparently fixed in
Fedora 12's 2.6.31.


I'm just curious what kernel was running on the thin client (or what is
running on the booksized PC now).  Could you please show me the output of:

$ cat /proc/verison

Thanks,
Regards,
