I am having the same problem and for the time being I solved it by inserting audio system's cable in audio port of tv-tuner, instead in motherboard's port.This means that I can't listen to operating system but can listen to tv tuner.Mute(by pressing m) works in tv time when I do this, although volume control is not supported, because tv tuner is not sound card of mother board.
