Sound "slowdown" on sis7012 hardware

[Thomas Schlesinger <schlesinger@xxxxxxxxxxxxx>]

Hi,

I have built-in sound (sis7012) on my desktop machine. It sounds to me, that 
sound files are being played a little bit too slow. The voice of singers and 
the "height" of music instruments seems to be to low, compared with playing 
the same music on the same machine with Linux.

I use the snd_ich and snd_pcm kernel modules on 1.7.0-DEVELOPMENT. From the 
syslog:

[..]
pcm0: <SiS 7012> port 0xd800-0xd87f,0xdc00-0xdcff irq 10 at device 2.7 on pci0
pcm0: <Unknown AC97 Codec (id = 0x434d4982)>
[..]

Sadly I have no measuring equipment to confirm my impression, I have tested 
this with mpg123 and the Amarok music player.

Any ideas how to fix that?

Thomas
