[Gentoo] How do I configure alsa on an IBM Thinkpad 600?

I've already re-compiled my kernel using genkernel so that alsa and cs4236 (Neomagic) support are included (following the steps at http://www.gentoo.org/doc/en/alsa-guide.xml) but I cannot get alsaconf to successfully probe cs4236 (No legacy cards found).

Supposedly I need to manually configure alsa, but I haven't the slightest clue how to do so.

here's some info for the sound card.
I used to have 600E and I recall it needed some special tinkering in order to work. IIRC the alsa detected it wrong and it needed to be manually setup in order to get it to work.
You can google for it though if the thinkwiki link doesn't help you.

Hi!

Did you try modprobe snd-cs4236?

If you want to set up ALSA manually: open /etc/modprobe.conf in your favorite editor and add these lines -

alias snd-card-0 snd-cs4236
alias sound-slot-0 snd-cs4236
options snd-cs4236 index=0 port=0x530 cport=0x538 isapnp=0 dma1=1 dma2=0 irq=5

I've compield the module into the kernel so it doesn't need modprobing (and if it does it is automatically done at startup).
Alsa configuration is my problem - I'll try those lines now.

I'll use the /etc/modprobe.d/alsa file instead then, and then run update-modules

Alsamixer now works, but I have yet to get sound to come out. Possibly I need to re-compile some apps with the alsa flags.

EDIT: With every single slider at max and the laptop sound controls (FN + Pgup/Pgdown) up I tried to run speaker-test.
However it spews the error message 'Playback open error: -16,Device or resource busy' every second with not a peep coming out of the speakers.

EDIT2: I'll try the configuration from http://bugtrack.alsa-project.org/mai...:Module-cs4236
