I replaced default.pa with the one extracted from the deb mentioned by @David but, in my case, it did not fixed the issue, so as @Hui said there can be several underlying issues causing the same problem. In my case (Dell XPS13 7390) the kernel module used is btintel with device firmware: intel/ibt-20-1-3.sfi. I have verified with btmon that when I switch from adsp to hsp/hfp it stops showing packages coming from the headset. @Corey to extract the file you just have to run something like: dpkg-deb -x pulseaudio_11.1-1ubuntu7_amd64.deb pulseaudio -- 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
