For some reason, when Bluetooth headphones are connected to my macbook the volume control doesn't have any effect on the headphones volume. They seem to be stuck on full volume and doesn't change when I lower the volume.
I've tried 'sudo killall coreaudiod' in the terminal but it doesn't change anything. Have restarted and re-paired the headphones but no joy. Any similar solutions haven't worked either.
Anyone got any ideas?
