The way to set and save with ALSA is:
Issue as a normal user
mingdao@paul:~$ alsamixer
and set your volumes.
Then su to root and issue
root@paul:/home/mingdao# alsactl store
Hope that works for you. I'm running Slackware 10.0 which has sound
in Fluxbox, but not in KDE. Mandrake 10.0 Official has sound better
than I've heard in any of the 3 other Linux OSs or 2 Windoze OSs I've
run on this box.
If that doesn't help you, search LQ and
www.google.com/linux, as the
sound issues in Linux are screwed up, and so it's been asked a whole
lot of times. Screwed up, as meaning, there is no one standard for sound
like there is in Windoze. Ever distro, and desktop environment, and window
manager seem to do it differently. :/
