macbook bluetooth audio connected but silent
When I connect my Macbook to an external Bluetooth sound adapter, system prefs show that it is connected, but there is no sound. I have already verified the following:
- I have a mid-2015 MacBook Pro, running version 10.13.3 (17D102)
- System prefs (and icon) show that bluetooth is connected to external speaker adapter.
- Volume is not muted.
- Sound works fine with internal speakers.
- Other devices (Android phone and table) connect to external speaker BT adapter and play audio.
I did not have this problem before a recent software upgrade. Does anyone else have this problem and have they found a solution?
MacBook Pro with Retina display, macOS High Sierra (10.13.3)
