As workaround a mix between Oliver's solution and this in the duplicated thread (https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1871794/comments/25) worked for me on Ubuntu 20.04 / kernel 5.4.0-42-generic / MSI Prestige 14 I removed from my system /lib/firmware/intel/ibt* and copied /lib/firmware/intel/ibt* inside linux-firmware_1.183.2_all.deb (http://archive.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux- firmware_1.183.2_all.deb) Didn't have to make any changes to /etc/pulse/default.pa but reverted the audio configuration to default by removing ~/.config/pulse -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1878194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
