I'm trying to use a certain program through my stereo mix and have only that program go through, while being able to retain the sounds from other applications that I'm currently running. Stereo mix as far as I can see only allows you to transmit all of your application sounds unless they're muted via the mixer or their own internal settings, which isn't going to work for me.
Is there any way to just pass only one specific program through my stereo mix (or a virtual audio driver), while being able to keep all my other sounds?
