Why does muting sound in Live TV mute all Windows sound?

[scajjr2]

Using a tuner card in my computer. When I mute the sound in Media Center Live TV, it mutes all the Windows sound. Any way to get around this? Would like to be able to mute the Live TV & run closed captioning while keeping all the other Windows sounds. Can't seem to find any options to set.

Tuner card is a Avermedia M791-B, OS is Win 7

I would try using the mixer and manual mute from there, otherwise the mute is treated as a global comand

Is useful the mixer that is now separated by applications now.
