Well, usually killing the sound daemons (with "killall -9 artsd") and then
removing and reinserting the sound module ("rmmod cs****" and
"modprobe/insmod cs****" I don't remember the number as I write this email
from a i386 system, the sparc one is at home) that should do the job.
On the 2.2.* kernels the mixer interface is still buggy (the sound driver for
the sun systems is still in experimental state). Instead in the 2.4.* ones
the mixer works a little better, but in this one there's another problem
related to the short sounds, something like the click sound, that doesn't
close the sound card, leaving it in a bad state (for this one usually I use
the mpg123 player to restore the state, as to not remove/reinsert the sound
module), and also there's a problem opening the sound card from some
applications at a different output frequency than 44.1 KHz. Usually for the
two kernels the use of a sound daemon can solve the problems. For instance in
2.2.* kernels I change the volume using the esd libraries (that's working
well even when the sound daemon is not started) - by using the xmms player
for example. For the artsd daemon its arts control process (found in
multimedia menu) works very well for me (I use now KDE2.1). As to change the
output I think that the best solution remains the audioctl application. (well
you can use it also to change the volume by setting play.gain=[0..254], on my
system, when I use 2.2.* kernels, the 255 value blocks the sound card). I
don't remember exactly if in 2.4.* kernels the mixer was allowing the change
of the output port. On my computer I use some scripts to save and restore the
sound card state at the boot/shutdown time, so I don't have to use too often
the mixer. I use only the sound daemon's mixer to adjust the volume.
