I've just freshly installed lubuntu 20.04 (from 18.04) and am trying to record audio commentary to CAD work using OBS.

Unfortunately, I can pair my bluetooth headphones (Sony WH-CH510) and hear audio, but not record anything.

Trying in Blueman and looking at pauvcontrol-qt, it seems my headset is connected to the A2DP service, and the HSP/HFP service is unavailable. Could that be the issue - do I need HSP/HFP to somehow work to use the mic?
