Comment 2 for bug 1242763

Perhaps I wasn't clear enough, in Mixxx I have my outputs for each Deck individually set in the outputs panel see: http://mixxx.org/manual/latest/_images/Mixxx-111-Preferences-Soundhardware.png

These outputs are individually routed to my analog mixer so I can cross-fade, etc using my analog mixer (DJM 600). My mixer has a master output of it's own, independent on Mixxx's. I can route the output of my analog mixer back to my computer very easily.

I'd like to be able to use the built in recording and broadcasting functionality built into Mixxx, however I can't because the Master within Mixxx doesn't really correspond to the Master from my analog hardware mixer. There's no way for me to tell Mixxx, "record and broadcast from this input."

I think the simplest way to solve this problem, without necessarily overriding Mixxx's master output, is to let the user pick the input device they want to record/broadcast from. This would be an extra set of drop-downs in the Sound Hardware -> Preferences -> Input view.
