[ltp] Sound

[Bernard Tremblay]

Hi,

I have exactly the same thinkpad with Mandrake 10.0.  The module cs46xx
should in theory work but it won't.  It's been broken in some way for
the thinkpad.  I use the snd-cs4236 with alsa.  You have to specify
parameters for your module in /etc/modules.conf.

Here is an extract of mine:

--------------------------------------------
options snd device_mode=0666
alias snd-card-0 snd-cs4236
alias snd-slot-0 snd-cs4236
above snd-cs4236 snd-pcm-oss
options snd-cs4236 port=0x530 cport=0x538 irq=5 isapnp=0 dma1=1 dma2=0
alias char-major-14 soundcore
alias sound-slot-0 snd-cs4236
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-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
---------------------------------------------

It sometime happens that the module stop working.  Then just unload it
and reload it (rmmod/modprobe) and it will start working again.

The dma1/2 parameters value may sometime have to be inversed to work
depending of your sound chips.  Mine is a Cirrus CS4610/1 Crystal Clear
Sound Fusion.

Let me know if you get your sound to work.

Regards,

       BT
