Okay - I found on another thread ([Deprecated] [TESTING] Bluetooth audio streaming (A2DP) - #140 by DBMandrake) DBMandrake said that a2dp package unlikely to work with hifiberry DAC+, which I have installed. So I guess that’s that.
However, I still am trying to ascertain whether the BT dongle I got from OSMC store is actually functioning properly. I have not had any luck getting it to connect to anything - not a phone, tablet, computer or BT receiver. Sometimes the devices show up in the OSMC networking screen (although I have had my iphone sitting literally on the dongle for the last 30 minutes and it hasn’t), but pairing never works and none of the devices have ever discovered the dongle.
My plan was to stream from devices to OSMC, then output to speakers via Hifiberry DAC+, but although that doesn’t seem possible right now I would like to confirm whether my dongle actually works. I assume the presence of the DAC won’t affect the ability of the system to pair with devices, right?
