I wish to use a mac mini as a home theatre system.
I would like the mini to send commands to the power amplifier to turn on/off depending on whether there is any sound generated (like a screen saver but for sound).
Anyone have ideas on how this can be done?
Power Amp is Cambridge Azur 650R, which can be controlled by IR or RS-232.
Amp manual says not to keep on at all times, and I wish to conserve energy.
I am looking for something equivalent to the 'Sleepwatcher' utility (for the display, that I will use with my projector), but which works for sound.
I have found that the HALLab utility, from apple's XCode developer kit, can show that sound is 'Running somewhere', so it's possible in software.
Anyone know of a tool that uses this? Or which library calls I could use to do the same thing as HALLab?
