[ltp] Sound on ThinkPad T22

[Mack Stevenson]

Hi Andrew,

Glad to know the ALSA drivers worked for you. I own a T21, with the same 
sound chip, and never had such luck.

But yesterday I found out that the cs46xx driver in the _2.4.7_ kernel works 
perfectly. You only need to append

alias sound cs46xx
options cs46xx thinkpad=1

to your /etc/modules.conf.

HTH someone,

Mack
