hi Christian,

attached is a little patch, that adds a toggleMute function to the dcop
interface of kmix. i've found this quite comfortable in combination with
khotkeys, to have a single button mute/unmute sound. well, one can do the
same without that patch, but you'll need to write/run a shellscript then from
within khotkeys.
hope to see this in kde 3.3

thanks
Florian Ehrenthal
