Re: problems with Via AC97 controller

But when I try the test I hear no sound and get:

modprobe provokes the following error

Can you help?

The via82cxx_audio module is failing to intialize. This could be because the chipset on your mobo is a newer version than what the driver you have supports.

I have this audio chipset on my mobo at work. I had problems with older kernels. At one point (2.4.20 or 2.4.21) the modules would load but I'd STILL get no sound. I'm currently running 2.4.22 and its working. Modules loaded are:
via82cxxx_audio        20988   0
ac97_codec             13428   0 [via82cxxx_audio]
soundcore               3844   2 [via82cxxx_audio]

chipset info:
00:11.0 ISA bridge: VIA Technologies, Inc. VT8235 ISA Bridge
00:11.1 IDE interface: VIA Technologies, Inc. VT82C586/B/686A/B PIPC Bus Master IDE (rev 06) 00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97 Audio Controller (rev 50)

I'd suggest seeing what modules the stock debian kernels support and if possible upgrading your kernel via apt-get or compiling your own.
