DJM 450 Macbook USB/AUX no sound

@Keimo > If you select the computer icon, that needs you to send some signal to it from your computer in order for there to be any output audio.

Yes, no sound, as I said It's working on the two channels but not on the aux. So it's hardware then

I'm sending audio from my computer but no sound/signal when I select the computer sign on the aux, when I'm selecting it on the two other channels, there's audio and signal.

Right ... but what are you sending to that AUX channel?

Well I select the audio in my settings djm 450, and sending music from iTunes or internet, ableton, not working in either case

Sorry, but only Ableton would be able to use it - the others can only address the first pair of outputs, but the AUX is output 5/6.

Hi, 

I am having a similar issue, however I am using Rekodbox. I have installed the correct drivers for the DJM 450 on my Macbook Pro, though in Rekordbox audio settings there is no option to select the DJM 450 as an output (ive seen in other forums a DJM 450 option), only the built in output option for the Mac speakers. There is also no option for internal or external mixer mode (not sure if related, again I've seen this on other forums). Additionally the DJM 450 is recognised as connected in the DJM setting utility. 

Attached are some screenshots so you can see what I'm seeing

Thanks!

Joey
