[ltp] Sound problems on A21m

Hello all,

    I just got a new TP A21m and installed RedHat 7.0 on it. Everything went
smoothly (well, except I don't think the modem works, but the ethernet does
and that's all that matters) except for the sound. So after looking around a
bit I found out that I had to disabled Power Bus Management in the BIOS and
add a thinkpad=1 to the arguments for loading the module.
    So now my Crystal Soundfusion works, except it plays WAV files way too
fast, and the sound is a LOT quieter than when I boot my Windows partition.

    I notice most other people on the list are using the ALSA drivers,
whereas I'm using the CS46xx drivers which were detected on install, so I'm
wondering if that would be the problem, but I also noticed that Thomas Hood
said that IRQ 9 is reserved, and according to Win2000, my sound card is
using IRQ 9... however, if it's PnP, shouldn't Linux be able to reconfigure
this on startup? and if not, is there some way I can do it?

Thanks in advance
