- I've started the (ad-hoc configured) pulseaudio
- Connected the headphones
- Opened a video in VLC
- nothing from the HPs
- opened pavucontrol
- the VLC output was set as HPs; under `Configuration`, the profile was `A2DP Sink`
- Changed profile to `HSP/HFP`
The sound was now playing through the HPs.
In real world use case, I would switch again to A2DP, but it's irrelevant for debugging (I assume everything works as expected the moment I switch profile).
OK, log is attached.
