I'm experiencing this issue as well. On the HSP/HFP profile, the audio output comes through crystal clear, but the microphone is lost. On the A2DP profile, I get the microphone back, but the sound quality on the headphones becomes terrible... sounds like I'm on a copper phone line or bad cell signal. - Kernel: 5.8.0-48-generic - OS: Ubuntu 20.04.2 LTS - Machine: Lenovo ThinkPad T-490 - Headset: Bose QuietComfort 35 II -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio 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.
