Noticed that I couldn't use my headset mic on any apps in the past month, but
the above reports are describing the same behavioural issues as I am seeing soI
think I am hitting the same problem.
Using Sennheisser HD 4.40BT headphones on a System76 Gazelle. Connects default
audio through headphones with the A2DP profile as expected when connecting
through BT, but the Internal Microphone stays selected for input. Trying to
select the HD4.4 microphone setting does nothing, and no signal of any kind
comes through the input.
Switching to the HFP/HSP profile also leads to a break in audio, and
after the A2DP setting is shown as unavailable until I wipe the userland
pulse configs. It cuts off the audio through the headset and ends up in
a bad configuration where I have to turn BT off and on again to
reconnect and when it does, the configuration is stuck on HFP/HSP and in
mono.
No audio through the headset mic can be picked up through any
pulseaudio-enabled monitors, all showing zero input with whatever
configuration or set-up I can muster.
Running Linux pop-os 5.4.0-7642-generic #46~1598628707~20.04~040157c-

Title:
[Sennheiser HD 4.50 BTNC] Bluetooth headset not working when selecting
HSP/HFP audio profile in Focal Fossa
Status in bluez package in Ubuntu:
Confirmed
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
After updating the release from Ubuntu 19.10 to 20.04, the bluetooth
headset doesn't work anymore when HSP/HFP profile is selected.
With Ubuntu 19.10 the headset was working, there was audio and the mic
was perfect for video conferencing.
[Steps to reproduce]
1. Connect headset (used blueman to setup and connect)
1.1. When connected the system automatically selects A2DP profile
2. Start playing audio (browser or other)
3. Change profile to HSP/HFP with pavucontrol (or blueman)
4. The audio disappears and microphone is not working (no input)
5. Optionally switch back to A2DP and the audio comes back
[Expected]
When switching to HSP/HFP the audio should keep playing and the microphone
should start working
[Notes]
I tried with pavucontrol to switch between profiles while playing audio from
a browser.
As side note there's a led in the headset that still blinks when switching
profile.
I tried deleting the pulse folder under user's profile .config without
success, also reinstalled packages and did a `sudo alsa force-reload`
and rebooting several times.
Note: not sure this is a duplicate of [Bug #1576559], it looks quite
different since the profile changes but the headset stops working.
[System info]
Ubuntu: 20.04 - Linux 5.4.0-29-generic x86_64
pulseaudio: 1:13.99.1-1ubuntu3
