Deaf sink when call active (HFP), bluetooth MOMENTUM 4 headset

- AD2P / aptX works just fine
- When headphones get switched to headset during the call (to HFP), no matter what Profile is selected in Pavu control, no sound is coming out (microphone seems to work)
- Headset did work fine couple of weeks back
- Sennheiser MOMENTUM 4 headphones, firmware 2.13.28 (up to date as of now)
- I have pipewire + wireplumber installed (no special configurations at place), no pulseaudio
- Pavu control HFP options: [ Headset Head Unit (HSP/HFP, codec CVSD); Headset Head Unit (HSP/HFP, codec mSBC); Headset Head Unit (HSP/HFP) ]

Any idea how to find the right profile/port that could be set via pactl?

Restarting pipewire `systemctl --user restart pipewire` at least enables to select aptx mode again.

Re: Deaf sink when call active (HFP), bluetooth MOMENTUM 4 headset

wireplumber in the last two releases changed a lot in how they handle BT, maybe check whether downgrading that a version helps.

As for ports via pactl that will be a profile change, so check

pactl list cards

instead.
