Subject: Mickey mouse voices on snd-intel8x0

Hi,

I have a Compaq Deskpro EN with PIII/866 recycled as a thin client.
The problem was that sound on the thin client was played faster than it
should.
I have Fedora 9/x86-64 on the main machine, so the thin client is LTSP5
that comes with F9.
I tried everything (acpi=off, etc) but the strange voice didn't get better.
I discovered this in the dmesg:

intel8x0_measure_ac97_clock: measured 50895 usecs
intel8x0: measured clock 78 rejected
intel8x0: clocking to 48000

I looked at the current kernel sources and found the solution for that.
I had to provide this for the thin client in
/opt/ltsp/i386/etc/modprobe.conf :

options snd-intel8x0 ac97_clock=44100

# lspci -s 00:1f.5
00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97
Audio Controller (rev 02)
# lspci -ns 00:1f.5
00:1f.5 0401: 8086:2445 (rev 02)

Best regards,
Zoltán Böszörményi
