How do I get clear audio on to my FB live feed from My DJM 900 nexus 2 from iphone7?

So i recently got the new Iphone 7. before I had the 6 and was using this method to stream clear audio.

Obviously the iphone 7 no longer has an audio jack so Id like to find an effective way to get clear audio on to my live FB feed.
I have tried plugging the phone in via usb straight into the mixer but it at that point mutes any sound that the phone could receive.

Is there a better option for me? would using my computer be better? how would i route audio in facebook to broadcast what is being sent out from one of the USB ports on the DJM. help? =)

I just hate having the acoustics being heard in the video stream.

I think you can still stream via your phone using an extra adapter to charge and use the audio jack at the same time (not sure if this will work with audio input tho), check: http://www.belkin.com/us/p/P-F8J198/

just use a Webcam and OBS with facebook live
