Okay, so I run Win7 and have a monitor/speaker set up and then I have an HDMI cable that runs from my video card to my TV with both displays being separate, yet always active. The latter I generally use when watching shows and such. Of course, when I want to do this, I don't want sound coming from my PC speakers, resulting in a process where I have to manually toggle the default playback device between them and the TV.
Basically, I'm looking for some kind of script or program that can just do this in one click, no fuss. Suggestions?
