cmd line way to mute line in realtek hd audio card
I have a line of music audio entering my realtek card to accompany a powerpoint slideshow, together they go out on our community cable channel. I need to kill the input, the music audio that is directly plugged into the card in the back of the pc, so that when I schedule a video (bod meeting prerecorded video), the line in is muted and the video audio goes out, without the muting capability I get both streams...
Need to do it in an attended way. Also, need to return to the music input afterwards. Old config (xp/machine Creative sound card, allowed us to do this via a batch file that executed a muteon.exe, ran the video, then muteoff.exe...however the .exes do not work in our present config.
Any ideas greatly appreciated! It's burning me out...
