32 All Gnome's volume/mixer applet does, AFAIK, is the same as alsamixer,
33 on a less cli/ncurses interface... just volume control for the
34 channels the card tells the driver to tell the alsa subsystem it has
35 ;) ... it doesn't have anything more, really, to do with the actual
36 'mixing' than that, and it works just as well without it, as evidenced
37 by my netbook with ratpoison, no arts, esd, pulseaudio, etc...
38 listening to a radio stream on one aterm that's running mplayer
39 (outputting to bare alsa) and getting prompt and proper alerts from
40 Skype at the same time.

42 'Course, all the anecdotal evidence in the world won't make the
43 problem the OP is seeing.
