Disable aptX in bluetooth sink-inputs

I am trying to play audio from my android on arch using bluetooth. By default, aptX codec is selected which results in horrendous cracking of sound. When I switch codec to aac then audio quality is restored, but I can only do this from my smartphone.
I would like to change the codec for sink-input from within arch or disable aptX altogether. I tried to do this using pactl send-message, but it always fails saying "Send message failed: No such entity". I tried but cannot understand why this is happening.

If your phone only sends aptx/aac depending on your choice  then you indeed need to change this on the phone. Or can you switch in e..g pavucontrol?

I cannot do it inside pavucontrol as there is no option. I was thinking of changing some config, if it exists, so that my android just doesn't get to know that aptX is available. I saw using wireshark that when bluetooth connection is established A2DP capabilities are shared, and among them one is selected. So if arch doesn't send the message mentioning aptX, that would solve my problem.
