Bluetooth headset random disconnects AX200

[Almer S. Tigelaar]

[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.

[Almer S. Tigelaar (almer)]

I can confirm that manually copying the files in https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=73144e02dcff54529ab42d951de682740d204180, and rebooting, seems to reduce the disconnects, though I am still experiencing them.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Aidan Chappuis (zoup123)]

I can confirm this affects me on 1.197.2 (problem started on 1.197.1). Ax200 (Discrete in an m.2 e slot)

[Cruz Fernandez (cruz-fernandez)]

I've copied latest linux-firmware (a few days ago 20210919) and my setup has improved. I believe more patches on latest one have reduced this problem. I'll post more on the week when I confirm more.

[Almer S. Tigelaar (almer)]

Updating to linux-firmware 1.201 seems to have solved the problem for me.

[Anton Sudak (anton-sudak)]

Confirming, did not see any disconnects for past two weeks.

[Hadrien Mary (hadim)]

I still have the issue on Ubuntu 21.10 with linux-firmware 1.201.3

[Alex Haan (alexhaaniwink)]

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.

[shao.lo (shao-lo)]

I'm using Ubuntu 21.10 with firmware 1.201.3 as well. I have the periodic drop out followed by a static corruption. I was hoping it was an issue with the bluetooth dongle I use, so I bought a new bluetooth 5.0 version, but the problem persists. It will be good for hours (sometimes days) and then it will start happening every few minutes.
What is the time frame on a fix for this? Is downgrading the firmware the current solution?

[Hadrien Mary (hadim)]

I still see the issue (last time was after 90 minutes during a conf call) with Ubuntu 21.10 with linux-firmware 1.202.

[Aidan Chappuis (zoup123)]

I still see this as well, but instead of a total dropout, it drops out for a second then reconnects, but either swapped to the HFP profile or with several seconds of delay in the sound

[Laurent Dumont (baconpackets)]

Seeing this on 21.10.

[Juerg Haefliger (juergh)]

Can you test the jammy firmware to see if that makes a difference? There are quite a few AX2xx updates in there.

https://launchpad.net/ubuntu/+archive/primary/+files/linux-firmware_20220302.gitee0667aa-0ubuntu1_all.deb

And can you all report what adapters you're having problems with so we know which binaries need updating? Maybe so: 'sudo dmesg | grep -i bluetooth'.

[Laurent Dumont (baconpackets)]

Sure! I'll install the deb.

I still experience this issue with Jammy 22.04, with the 20220329.git681281e4-0ubuntu1 version of linux-firmware.

[Juerg Haefliger (juergh)]

For people who believe they're still seeing this issue with Jammy 22.04, please attached the outputs of dmesg and 'lspci -nnv' from the affected machine from when the wifi problem occurs. We might be dealing with different issues and/or wifi hardware.
