Installing Slackware Linux Part 5 - Configuring Audio
Slackware
9.1 ships with the ALSA (Advanced Linux Sound Architecture) system. I
had never really used it before, beyond manually loading ALSA kernel
drivers without having any of the utilities installed. It's
considerably more complex than the older OSS (Open Sound System)
drivers, requiring more kernel modules and module aliases to be set
up in a modules.conf file. I thought I was going to really hate it,
but when I saw how easy it was to configure, I had to re-evaluate
that.
As root, type alsaconf and a curses based
configuration utility will appear.
It
probes for your sound card.
Offers
to set up your modules.conf file for you.
Some
nice informational messages.
That
should be it, your audio should now work!
If that doesn't work
for you, then it will be manual configuration. Check the Alsa
Soundcard Matrix to see if your card is supported, and what module to
use.

As
for configuration, this is what you'll want to put in your
/etc/modules.conf file. The lines should pretty much be the same for
all sound cards, but what you must change is the driver module, which
I have shown in bold.
Some
cards may need additional modules or options. See the "details"
section for your card, at the Alsa Soundcard Matrix.
