a2dp профиль в bluetooth наушниках доступен только после рестарта сервиса
При первом подключении ушей, «High Fidelity Playback(A2DP Sink)» не доступен, есть только «Headset Head Unit(HSP/HFP)», который звучит ужасно. После systemctl restart bluetooth, «Headset Head Unit(HSP/HFP)» не доступен, а «High Fidelity Playback(A2DP Sink)» появляется, правда, чтоб появился звук, надо ещё зайти в pavucontrol, переключить профиль, например, на «off» и обратно на «High Fidelity Playback(A2DP Sink)». Если перезагрузить bluetooth ещё раз, всё возвращается в исходное состояние(headset_head_unit - присутствует, a2dp_sink - нет).
После перезагрузки сервиса, в логах следующее:
> systemctl status bluetooth

Разнообразные танцы с бубном вокруг /etc/bluetooth/main.conf вроде отключения headset_head_unit профиля не помогают.
В чём может быть проблема и какую ещё информацию я могу предоставить, чтоб было понятнее, в чём проблема?
