Bluetooth devices not playing sound and disconnecting from Macbook Pro in 5-10 seconds
Good day, the following same occurs on two devices that are connected via Bluetooth - speakers and headphones.
Bluetooth on Macbook Pro is turned on, either Bluetooth speakers and/or Bluetooth headphones are fully charged and turned on. Either or both speakers and headphones are visible in the "Devices" list under Bluetooth icon in Menu Bar.
I am able to connect the speakers and headphones via Bluetooth, i.e. for 5-10 seconds speakers and headphones are shown as "Connected" in System Preferences/Bluetooth. Also, when connected via BT the speakers and/or headphones play a short (~1 sec) tune which indicates they are connected. However, when using e.g. Spotify or VLC on MBP, no sound is heard on either speakers or headphones. Both speakers and headphones disconnect 5-10 seconds after connecting (tried at least ~20 times) without having played any sound.
Further info:
- These headphones and speakers are connecting and playing sound properly on my iPhone;
- MBP macOS: Big Sur 11.0.1 (same issue was present on Catalina as well);
- Neither speakers nor headphones are visible in "Output" list in System Preferences / Sound when they are connected via Bluetooth;
- Neither speakers nor headphones are discovered using Audio MIDI -> MIDI Studio -> Bluetooth Configuration, i.e. "No devices found" (neither when in System Preferences / Bluetooth speakers and headphones are shown as "Connected", nor when they are not shown as "Connected" but are visible under Menu Bar Bluetooth icon).
I tried (to no effect):
- turning Bluetooth on/off on MBP, headphones and speakers (multiple times);
- dis- and reconnecting MBP and the headphones/speakers via Bluetooth (multiple times);
- Shift+Alt+Click Bluetooth in Menu Bar, "Reset the Bluetooth module" (at least 10 times);
- quitting "bluetoothd" and "coreaudiod" processes via Activity Monitor (multiple times);
- deleting "com.apple.Bluetooth.plist" in /Library/Preferences (2 times).
I would be very happy to receive some further advice how I could proceed to start hearing audio on the bluetooth devices. Thanks in advance!
