I was reading this thread and I wanted to say I have a similar problem
with a twist.
I am running F9/x86-64 on my main machine, it doesn't have problems with
sound.
I am also running a 32-bit LTSP5 thin client, everything is set up
according to
the Fedora k12linux/ltsp docs. The client machine is a Compaq Deskpro EN
with PIII/866 CPU. And everything I tried on the thin client (software
running
on the 64-bit machine actually, sound is transferred to the client's
pulseaudio
daemon) is played quicker. Youtube videos keep the video and sound in sync,
so the video as a whole is played faster. Some other software that prefers
syncing audio to the video speed produce dropouts in the sound.
My son especially notices it in ScummVM...
Watching time go on the thin client console (Ctrl-Alt-F2) didn't show
anything suspicious. One second seems to be really one second and
installing ntpdate/ntpd into the thin client didn't change the faster sound.
Talking to myself, it seems. :-)
The solution for me on the thin client was to add a module option:
[root@db00 etc]# pwd
/opt/ltsp/i386/etc
[root@db00 etc]# cat modprobe.conf
options snd-intel8x0 ac97_clock=44100
