to find out, use lsmod.  If you see a bunch of snd* modules, you're using 
alsa.  If you can't tell, use locate to find the modules you do have 
loaded.  OSS modules are in .../kernel/sound/oss/

How do you know this?  I couldn't find anything in kmix that told me whether 
it was using alsa or oss.  I'm curious, because I'd like to know what my 
kmix says I'm using.

emulation mode means alsa is emulating the oss interface.  So, applications 
that only know oss talk to alsa, and alsa translates from oss speak to alsa 
speak, and plays the sound (or whatever).

You are correct, it's an alsa module, but its job is to provide a mixer 
interface to oss speaking programs.

Don't be afraid to install alsa-utils.
