Audio routing

There is audio routing built into Mon2Cam, which you can use with the -s flag. It's interactive, so it's not hard to use, but keep in mind that it may still have bugs. Also, it probably introduces some latency, however this wasn't tested and is probably quite tiny. (I haven't noticed any difference.)

Mon2Cam will try to detect if discord is trying to record, and then switch it's input to the Mon2Cam combined sink, but you may have to do it manually. You should also disable echo cancellation, because discord will detect most audio as echo.
