I am new to Linux and Debian and have really no idea how to
troubleshoot things yet. I had a local Debian guru help me install
Debian (on the 11th), but I'm having difficulties with my sound. Below
is the error message that I get:
Sound server informational message.
Error while initializing the sound driver:
device /dev/dsp can't be opened (no such device)
The sound server will continue using the null output device.
Here's my sound card info:
Crystal Semiconductor
Chip set CS4236
According to /usr/src/linux/Documentation/sound/CS4232 (where
"/usr/src/linux" contains the source file for your kernel), the CS4232
driver works for CS423x chips.

Did your Debian guru recompile your kernel? If so, he may not have
included support for the sound card (either as a module or built-in).

Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters
/lib/modules/2.4.16-686/alsa/snd-card-cs4236.o: insmod
/lib/modules/2.4.16-686/alsa/snd-card-cs4236.o failed

Unless you have reason not to, you might download the source for a newer
kernel (2.4.18 or so in Sid, I believe) and recompile with CS4232 (or
4236 if it's available) as a module.

The lspci command will list the PCI devices in your system. Since the
sound card doesn't show up, I would assume that the card is not a PCI
device. It has been my experience that PCI devices are a lot easier to
configure than ISA devices (unless the PCI device is really new, in
which case the support for the device may not yet exist).
I know it's frustrating, but keep plugging on. It's a different world,
but worth it.
