Hi Mitchell. I too use KDE, and have had problems with Kmix messing with mixer
settings on some distros.
Does KDE, when you login give you any message saying sound is not available?
I have Sarge. Etch, and Lenny available. Sid is a bit too near the edge for
me. Do you have the same sound problem booting from other kernels that you
have installed?
Looking back at mixer settings when you bootup. Alsactl restore should run
when you bootup, which will restore the mixer settings that alsactl store did
when you last shutdown. A problem I have had in the past is that Kmix will
alter these settings. To explain a bit more. Alsactl restore runs when you
bootup, and alsamixer's settings are as you left them when you shutdown. Now
you login to KDE, and Kmix enters the equation. Depending on the default
settings in Kmix, Kmix will change the alsamixer settings when you login to
KDE, and depending on the default settings in Kmix, you may have no sound
output.
I thought this problem had been resolved, but it's worth opening alsamixer on
the CLI (Konsole) when you are booted up, and logged into KDE. Have a good
look at all the controls that are there for your card. My alsamixer controls
are useless to you (audigy2 soundblaster (emu10k1)). Mixer controls are
soundcard specific.
Also have a look at Kmix's "Settings"/ "Configure-Kmix". The "Restore volumes
on login" box is the one that used to create problems. Make sure that it's
unchecked.
Which laptop/pc are you using?
Lots of patience, and one thing at a time. Hopefully the problem will be
resolved sooner, rather than later.
All the best.
Nigel.
