<html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hi, Is there a module that can run a (configurable) shell command when <ul> <li>sound output is needed, i.e. an application plays a sound, and it's not muted </li> <li>no sound output is needed anymore, after a certain configurable timeout, e.g. no sound played in the last 120 minutes</li> </ul> ? Effectively, this would work exactly like a screen saver, just for sound, not for the screen/input. Reason is the same: I currently have my amplifier and speakers running 24/7, because they are connected to the HTPC, I need them as alarm clock etc.. I would like them to turn off automatically when I haven't played any sound in 2h, and turn them on again immediately automatically when any sound is played. On the hardware side, I can use a power switch connected via USB. I'd control it with a simple shell script, and pulse would just call that, one command for "on", one for "off". I do not want solutions that constantly poll the state, using running pacmd once a minute or similar. Does that exist exist already? If not, I guess it wouldn't be hard? Ben </body> </html>
