i have recently reinstalled debian and my wheel mouse isn't working(wheel) here is my xconfig file:

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/psaux"
Option "Protocol" "PS/2"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
Identifier "Generic Mouse"
Driver "mouse"
Option "SendCoreEvents" "true"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
EndSection

and i was told to delete the bold, will that fix the wheel???

Change the line:
to
In the configured mouse section and re-start the X server. You do not mention what the sound problem is but check if you are a member of the audio group with the command groups if you are not a member then adduser user_name audio as root then log out and back in for the changes to take effect.

this is my error for the sound card when i run sndconfig:

You don't seem to be running a kernel with modular sound
enabled. (soundcore.o was not found in the module search path).
To use sndconfig, you must be running a kernel with modular
sound, such as the kernel images shipped with Debian Linux or
a 2.2 or greater kernel

i have debian 3.0r1 installed so i know the kernel is 2.2 or better

my sound card is :

Crystal CS4280 3D PCI Audio

Did you choose sound when you installed? If you did, try to recompile the kernel with sound as a module instead of in the kernel. Some things seem to work only as a module. I tried to compile it in the kernel and it wouldn't work (ESS 1868 ISA at the time). If you can insert it as a module now, that would be easiest. Try using modconf to see if you have the module available. Good luck.
