[Sussex] Debian install - No sound

[John D.]

Does anyone know where or what I need to look at to try and get sound out of 
my debian install?

So far, the only hint I've had is that when logged into root, I get a error 
message that says "/dev/dsp no such file or directory".

I have done some digging around and tried a few "hit or miss" things, but 
nothing has come of them, and I haven't got a clue what to try next.

regards

John
