I have an issue setting up my DDJ-RR with Mixlr and LiveStream. Whenever I select the DDJ-RR in Mixlr or Livestream as an audio output device (channel 1&2, 3&4 or 5&6) no sound will come trough. In Rekordbox DJ I select the DD-RR Master Output to be the output... It all seems quite obvious but it just doesn't work. I wonder if anyone managed to solve this on MAC El Capitan with their DDJ-RR or DDJ-RX. I also tried to tweak the MIDI/Sound setting and use SoundFlower but without any luck. Please help!
