I have a DVB-dongle to watch TV on my PC, problem is I cannot change the sound on the TV software without changing the volume one everything else, eg a youtube video, I would like to be able to change one sound level but not the other, for example mute just the TV. It seem the sounds are tied togeather I suppect this is a programming fault ('feature') on the TV software, and there is nothing I can do about it? I think I can seperately control sound other applications. ( I can). BlazeDTV is the television software. So it seems there is nothign I can do? Slidiing the volume control on Blaze TV slides the PC's master volume control so it looks like I am bbuggered? Not a major problem I suppose. Maybe I should hassle the company for a fix?
