There are many extremely light console based mixer programs that allow you to script volume changes. I use smixer on my PVR, should be easy to find on the net. So when my PVR does "play" I turn off the LINE volume which shuts off the volume from the TV, and turn on the PCM volume which enables output from the playback. When it does "stop" I turn the TV input back on again for watching live TV. I use aumix on my desktop which has a GUI, but you can also call it with command line parameters and it will work similar to smixer. I use this in my desktop bootup to set the volume to where I like it. -- Trevor Boicey, P. Eng.
