Good for you.

No, no. It's just the "mixer GUI for pulseaudio"

Again, no. ALSA is a driver infrastructure. Pulseaudio is a sound daemon (and
sits on top of -- among other things) ALSA. In your case, you are most probably
using both (unless you're doing sound over the net, for example).

What makes things a bit confusing is that ALSA also provides some user-space
tools.

BTW: I have sound, am running a combination of stable and unstable and
have no pulseaudio. So it's quite doable.
