[CM] no sound with latest kernels/alsa modules

[Noel Bush]

Thanks for the reply; my responses with requested information are inline
below.  Two other points in addition:

1. Even if I do something goofy like "cat /dev/random > /dev/dsp", I
hear absolutely nothing.  This used to at least make a horrible noise.

2. I notice that the "Master" control in alsamixer or gnome-alsamixer no
longer has a "mute" option.  Is it possible that it's somehow muted and
can't be unmuted?  The following doesn't work:

# amixer set Master 100 unmute
amixer: Unknown playback setup 'unmute'..

# uname -r

I have an SB Audigy, and I'm using the emu10k1 module.  Here's the lspci
output:

I've tried installing that, but I get the following error, even if I
have booted the 2.4.21 kernel:

rpm -ivh alsa-kernel-2.4.21-1.ll.acpi-0.9.4-2.cvs.i386.rpm
error: Failed dependencies:
        kernel-version-arch = 2.4.21-1.ll.acpi-i386 is needed by
alsa-kernel-2.4.21-1.ll.acpi-0.9.4-2.cvs

I presume I should not just force it with --nodeps, right?
