AFAICT:

PCM - pulse code modulation, the basic format of digitised
uncompressed sound. This control usually affects anything generated
from the computer itself, like system sounds, sounds from mp3's, sound
from video etc.

LFE - low frequency effect, the subwoofer. This will affect sound to
the output that connects to a bass speaker. Note this only works if
the computer itself is decoding 6 channel audio and splitting it up to
the speakers. The better arrangement is to pass through all such
sounds (ac3, dts etc) to an external amplifier for decoding.

MUX - not sure in this context!

Those controls are in windows too, but not as poorly named sometimes.

Don't forget that a given audio chipset/driver combination probably
has many more controls than your sound card manufacturer actually
connects to anything.

I haven't seen a linux machine with any particular audio issues for
quite some time. Most of my machines just work. My particular interest
is multimedia (mplayer, mythtv, xbmc) and the only difficult issue I
have seen is in the context of digital audio passthrough, but that is
pretty well OK for me now.
