[AD] Allegro Feature Request (all ports)

[Gillius <gillius@xxxxxxxxxx>]

I've noticed that in Windows, when I call set_volume, it changes the wav out 
sound volume for my card and does not change it back when the program exits. 
I think it would be nice if it did.  If it doesn't do this in Linux it 
probably should too.  Running my game shouldn't have a permanent effect on the 
user's sound settings.

I have a SB Live! Value card with Liveware 3 and am running the latest CVS (as 
of like 2 hours ago).
