[ltp] Sound on ThinkPad T22

[Andrew Crawford]

I was finally able to get sound working under Linux-Mandrake 7.2 on my 
ThinkPad T22.  Since I received no replies to this post, I thought I would 
forward the instructions in case anyone else ever wants to get sounds 
working on one of these notebooks.

This is the command to load the proper module:

   modprobe snd-card-cs461x && modprobe snd-pcm-oss

The sound on mine was muted by default so, I had to turn up the volume 
before I could hear anything.  This can be accomplished with aumix using 
the GUI or at a command line with something like:

   aumix -v 90 -w 90

Here are the correct lines for /etc/modules.conf:

   # ALSA cs461x
   alias char-major-116 snd
   alias char-major-14 soundcore
   alias snd-card-0 snd-card-cs461x
   alias sound-slot-0 snd-card-0
   alias sound-service-0-0 snd-mixer-oss
   alias sound-service-0-1 snd-seq-oss
   alias sound-service-0-3 snd-pcm-oss
   alias sound-service-0-12 snd-pcm-oss

Good luck.
