Hi
I've just build a mediacenter, and is about to construct an hifi
amplifier for it. Therefore i would like to know a way to make alsa
detect when nothing is playing at the output, and then run a external
command. And detect when something has started playing at the output,
and run an external command before any output is generatet.
This I would like to do, because I then could make an interface between
the amplifier and the computer to make sure that it does not use anymore
standbypower than needed.
Any help would be appreciatet.
Regards
Andreas
