Similar to How can I output audio to both of my monitors simultaneously in Windows 7? but I want to do something specific with my two monitors both having audio output.
In Windows I can configure VoiceMeeter to be 5.1 but only use 3 audio channels L, C and R. What I'd like to do is set it up so the left monitor left speaker is mapped to L the right monitor right speaker is mapped to R and the remaining two are mapped and duplicated to C
The test audio does show muliple channels are going through but after the L R channel it's quiet. My guess is I may have to do something with composite but I am not really sure what exactly. I also tried Banana but couldn't figure out what to do there either.
