just messed up mixer settings
when you use the surround outs you just can't use Master device to controll sound
no way around that one.
i suggest if you feel like it getting a mixer named qamix
if you know how to compile stuff written with Qt/KDE
read the README the thing comes with a great config file already setup for SB Live
(tip: you have to edit the makefile paths as the package does not come with a configure script)
it shows your controlls (like surround controlls in a box to themselves)
also might try the command line
you have to enable Capture and a Mic Capture device for mic to work
qamix also shows capture device as a seperate tab .
I would NOT mess with that endless string of EMU10K devices at the end of any mixer that shows them when it should not. Try your best to not save any changes you have made to these devices or delete
/etc/asound.state and restart alsa and see if defaults are restored (at least that's what i would do)
