sound problems on sony vaio (yamaha ymf-754

[vester keil <a9900876@unet.univie.ac.at>]

hi!

i am experiencing problems with my soundcard on a sony vaio pcg-sr1k --
the soundcard is yamaha ymf-754 and it has been working on my old suse
system using alsa drivers. since i upgraded to debian however i cannot
seem to get it to work. i've installed the alsa .deb's and selected my
card with alsaconf, i've been using kernel 2.4.2 with sound support, but
i just changed that and am now loading sound support as modules.

/etc/init.d/alsa start presents me the following output:

Starting ALSA sound driver (version none):modprobe: Can't locate module
snd no devfs available (even though using the kernel with devfs).

can anybody help me out?

thanks!
