[ltp] Sound on ThinkPad T22

[Andrew Crawford]

Greetings,

I have installed Linux-Mandrake 7.2 on an IBM ThinkPad T22 and have 
everything working except for the sound.  Based on postings to various 
forums, it looks like other people have been able to get the sound to work 
on other ThinkPad models with the same or a similar sound chip:

cat /proc/pci :

   Bus  0, device   5, function  0:
     Multimedia audio controller: Cirrus Logic Unknown device (rev 1).
       Vendor id=1013. Device id=6003.
       Slow devsel.  IRQ 11.  Master Capable.  Latency=64.  Min Gnt=4.Max 
Lat=24.
       Non-prefetchable 32 bit memory at 0xe8100000 [0xe8100000].
       Non-prefetchable 32 bit memory at 0xe8000000 [0xe8000000].

I have turned off PCI power management in the BIOS.

sndconfig identifies the card as:

   Cirrus Logic | CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator]

However, it then reports that it is not supported and exits.

I believe I have the correct module:

   /lib/modules/2.2.19-4.1mdk/alsa/snd-card-cs461x.o

I'm not sure I know what to put in /etc/modules.conf.  I have tried several 
different things, mostly based on the alsa docs.  In all cases, I get an error:

Starting alsa sound driver snd-card-cs461x Note: /etc/modules.conf is more 
recent than /lib/modules/2.2.19-4.1mdk/modules.dep
/lib/modules/2.2.19-4.1mdk/alsa/snd-card-cs461x.o: Hint: insmod errors can 
be caused by incorrect module parameters, including invalid IO or IRQ 
parameters
init_module: Device or resource busy
/lib/modules/2.2.19-4.1mdk/alsa/snd-card-cs461x.o: insmod 
/lib/modules/2.2.19-4.1mdk/alsa/snd-card-cs461x.o failed
/lib/modules/2.2.19-4.1mdk/alsa/snd-card-cs461x.o: insmod snd-card-cs461x 
failed

Manually doing an "insmod snd-card-cs461x" I get a series of undefined 
symbol messages.

Can anyone tell me what I need to know to get it to go?
