Problems with Sound on Toshiba Satellite 2800-400

[Florian Nykrin <flo.n@gmx.de>]

Hello!

I own a Toshiba Satellite 2800-400 and also Problems with 2.4.3
and Sound. I used the alsa-drivers for my Yamaha YMF754 and only
marked the Sound-Support as a Module (otherwise alsa complains of not
finding snd.o).
When I turn on PCM in the alsamixer I get a buzzing noise in my
Speakers. When I play a MP3 I can hear the music, but the buzzing
noise stays. When I turn of PCM it is gone.
I'm running Debian sid.

Has anyone the same problem (and solved it)?

Regards, Florian.
