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 ------------------------------------------------------------------------- Take Surveys. Earn Cash.
