Hi guys, I have been trying to get a good quality facebook live stream with audio from the mixer. I have a Rode SC4 running off an iPhone 5c but cannot get the iPhone to stop using the internal microphone even when the linein cable is plugged in. Has anyone had any experience of successful live streams with audio running from the mixer? I am using a secondary mixer to drop the levels and tested it using voice memos and works fine. Seems like the facebook app doesn't recognise a line in but surely that's hardware? Any help appreciated.
