I'm trying to disable/block media endpoint so that my laptop won't be
used as a media sink by Android devices. I occasionally use Bluetooth
for transferring small files fro and to Android devices. Whenever a
Android device connect to my laptop, it automatically enables "Media
audio" again. If the phone was playing music, the laptop becomes the new
media sink and the laptop speakers start blasting music :( What a
horrible idiot-proof design.
Google doesn't ever listen to anyone, so I figured it's easier to find a
solution by configuring my Linux machines.
bluetoothd output:
Endpoint registered: sender=:1.78 path=/MediaEndpoint/A2DPSink/aptx_hd
Endpoint registered: sender=:1.78 path=/MediaEndpoint/A2DPSink/aptx
Endpoint registered: sender=:1.78 path=/MediaEndpoint/A2DPSink/sbc
Endpoint registered: sender=:1.78 path=/MediaEndpoint/A2DPSink/sbc_xq
And bluetoothctl shows:
UUID: Audio Sink (0000110b-0000-1000-8000-00805f9b34fb)
I don't think Audio back-ends(ALSA, PA, PW) are not involved in this
device source-laptop sink set up. How do I prevent my laptop from being
used as an A2DPSink endpoint? Or if I can just blacklist a certain
kernel module, that'd be just fine.
