Thanks for responding Alwin... my sound card is the Personus Audiobox and both the SL viewer, FS, and Mixx are going through the headphones...as I have the Audiobox as the default it will only go through the headphones. With SAM Broadcasting software I was able to mute the broadcast. Mixxx does not seem to have that option...
I got Mixxx and it works great but I cant seem to be able to figure out how to silence Mixxx so I can here it in SL, I can silence the viewer but then don know if there are streaming problems. Any help to rectify this would greatly be appreciated
