I've compiled and installed the Alsa driver for my sound
card but there's still no sound. Linux detects my card and
the following is shown in X Windows:

Audio Devices
Vendor: Creative Labs
Model: SB Audigy LS
Module: snd-ca0106

ALSA states that all audio is muted by default and I have
to turn it back on with a mixer program, when I ran my
mixer program, I got the following:

Volume control is unable to run correctly.
Unable to open audio device '/dev/mixer'.

I run everything as root, so I'm sure I have the rights to
it.

Also, I tried the mixer provided by ALSA and this is what
I got after running "alsamixer":

alsamixer: function snd_ctl_open failed for default: No such file or directory

What do all these mean? Any suggestions will be appreciated.
