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- Ubuntu SMP Fri Aug 28 18:02:16 UTC x86_64 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1878194 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.
