This seems to be mostly solved in Ubuntu 21.10 (compared to 21.04. linux-firmware 1.201.3) for me now.
I do regularly (multiple times in a minute) get a hiccup which lasts a fraction of a second where there's no sound output. Not an issue for videocalls (other microphone than through the bluethooth headset to keep A2DP sink opposed to the crappy HFP). That hiccup isn't ideal when listening to music though. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1933771 Title: Bluetooth headset random disconnects AX200 Status in linux-firmware package in Ubuntu: Invalid Status in linux-firmware source package in Hirsute: In Progress Bug description: [Impact] Using several different bluetooth headsets I find that the Bluetooth functionality of the built-in AX200 module of my motherboard keeps randomly disconnecting. I found that this has been fixed in recent Linux firmware updates, but I am not sure that fix has landed yet in Ubuntu Hirsute. Herewith I am posting the link to exactly the issue I am having: https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1155 And the Linux Firmware commit that resolves this: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=73144e02dcff54529ab42d951de682740d204180 A related Fedora bug: https://bodhi.fedoraproject.org/updates/FEDORA-2021-93247f3274 It's difficult to relate the upstream kernel version firmware version in which this was fixed (linux-firmware-20210511) to the version of the linux-firmware Ubuntu package (for me). Perhaps someone can comment on whether this has been merged in. I am still experiencing disconnects with 1.197.1 at least. -- Description: Ubuntu 21.04 Release: 21.04 linux-firmware: Installed: 1.197.1 Candidate: 1.197.1 I expected: Bluetooth headset to remain connected What happened: Bluetooth headset connects, then randomly disconnects and reconnects while playing media [Test Case] See above. [Fix] Update AX20x firmware blobs. [Where Problems Could Occur] New firmware blobs so previously working adapter might now fail.
