Getting audio on Facetime video call to play on external speaker
Because of the ongoing COVID-19 outbreak, my son is having to take his cello lessons from home using Facetime. I purchased an Apple Lightning to HDMI dongle so he will be able to see his teacher on our TV.
The dongle works well; when we call up video from YouTube or Netflix it plays through the TV's audio system. But, when we do a Facetime video call the audio comes out of the phone although the video is mirrored on the TV.
I changed the settings under Call Audio Routing to Bluetooth Headset and connected to my Bluetooth speaker, but that didn't help. Is there some way to get the audio on the Facetime video call to play externally when hooked to an HDMI display?
