Hi,
I'm running vanilla 2.6.21.5 on a Winfast NF4UK8AA motherboard and sound is
playing at half-speed.
I get the following output in dmesg:
intel8x0_measure_ac97_clock: measured 51345 usecs
intel8x0: measured clock 29136 rejected
intel8x0: clocking to 48000
lspci says:
00:04.0 Multimedia audio controller: nVidia Corporation CK804 AC'97 Audio
Controller (rev a2)
I've tried passing various ac97_clock values but it seems to have no effect.
I've also tried setting ac97_quirk but that doesn't help either.
I attach my full dmesg and .config. Please let me know if I can provide more
information or help debug this.
Thanks,
David.

dmesg:

Perhaps you might want to try the acpi_use_timer_override bootflag?

I'm afraid that doesn't make any difference. I attach the new dmesg with that
flag set, in case it's helpful.
Thanks,
David.

Could you give the output of
lspci -vv -s 00:04.0
and
cat /proc/asound/card0/codec97#0/ac97#0-0
? You should run lspci as superuser to get all device capabilities listed.
I also added Jaroslav to CC.
