Random bluetooth speaker disconnects

mushotoku · 2021-01-26 19:49:22

Hi everyone,...

I'm trying to tackel an annoying problem with my Bluetooth Speaker, which randomly disconnets.
It happens at least once within 12h, often more than once. Even when the system is idle and not playing any sound.

# journalctl --no-hostname -u bluetooth.service  -b -1

This does not happen with the lts kernel, which runs fine, without any disconnects.

# pacman -Q linux-lts
linux-lts 5.4.92-1

So, I tested the following kernels one after another:

linux-5.10.1.arch1-1-x86_64.pkg.tar.zst
linux-5.9.14.arch1-1-x86_64.pkg.tar.zst
linux-5.8.14.arch1-1-x86_64.pkg.tar.zst
linux-5.7.12.arch1-1-x86_64.pkg.tar.zst
linux-5.6.15.arch1-1-x86_64.pkg.tar.zst
linux-5.5.13.arch2-1-x86_64.pkg.tar.zst

Sadly, all of the above versions are affected by this and had randomly disconnects.
So for now I'm stuck with the LTS Kernel from above, which works.

I also tried to disable various module options, which also did not help

btusb.enable_autosuspend=0
bluetooth.disable_esco=0
bluetooth.disable_ertm=0

Also disabling secure boot had no effect.

Some system info:

You ever fixed this? Same problem..

alatlantic · 2021-02-18 04:08:08

Also following this issue. Intel Corp. AX200 Bluetooth. My logitech bluetooth speakers just started doing this last week and drove me insane trying to fix. Nothing in any of the wiki pages helps, and I tried it all. It randomly disconnects, sometimes once an hour, sometimes much more often. More frustrating, they actually often appear connected and just stop playing sound, which is hell on calls.

The closest I can figure is that it likely isn't the kernel alone. Solus on 5.10 does -not- have this issue...which leads me to start blaming pulse perhaps? Trying the pulse bluetooth git modules didn't help a bit, either, sadly.

Unfortunately I absolutely need to be available for calls and didn't have time to resolve, but would be interested in what is found.

Damino · 2021-02-18 05:56:39

I also have this issue, with an AX200. My Bluetooth headphones started disconnecting around the same time as you guys, despite working on the same kernel for weeks prior. Happens with both PulseAudio and PipeWire.

Moopy · 2021-02-18 12:22:12

Same issue. My headphones are Sony WH1000XM2. Started only within the last couple days. I haven't tried reverting updates yet but I suspect some update broke it.

alatlantic · 2021-02-18 18:20:57

I had some time today to look into it, or at least capture some info.

Here are the relevant logs when the break happens. Actually, the log burst follows the audio cut out by about 10 seconds, if that matters.

I downgraded bluez from 5.55-2 to 5.55-1 and so far has been running uninterrupted for about an hour, which is a new record for this week. Will update later today if it holds up.
(fresh install, so shouldn't be some old file/setting stuck)

Edit - I was streaming music for 3 hours uninterrupted, then it happened again . Seems this isn't the fix either.

I can confirm that BlueZ 5.55-1 does not fix the issue for me.

Damino · 2021-02-18 21:06:16

I can't reboot my PC right now, but I wonder if anyone having issues recently (myself included) would benefit from downgrading the linux-firmware package.
Looks like there was an update for the AX200 10 days ago.

Downgraded to linux-firmware-20201218.646f159-1 and put bluez back. Will report if I find anything.

Edit:
1.5 days, zero disconnects - this definitely fixed it for me. Thank you!

I also got this problem with pipewire and bluetooth.

I was able to reboot. I've been running for 80 minutes with downgraded firmware and my audio just cut out for 5-10 seconds.
That being said, it came back without disconnecting, and my logs don't indicate any problems. Maybe I can rest easy and consider that a separate issue, as I'm using the Git versions of PipeWire from the AUR.

EDIT: With both repo and AUR PipeWire, my headphones still disconnect. Seems the downgraded firmware doesn't fix anything.
EDIT 2: After 3.5 hours, PulseAudio also disconnects.

Can confirm the issue, fixed it temporarily by downgrading linux-firmware (20210208.b79d239-1 -> 20201218.646f159-1).
Have been using my Sony WH1000XM4 with AX200 for a long time now, seems to not disconnect now.

Damino · 2021-02-20 00:14:44

I've been going a few hours today with no problems. Here's my list of downgrades:

linux-firmware: 20201218.646f159-1
pipewire, pipewire-pulse, pipewire-alsa, pipewire-jack: 1:0.3.20-1
bluez, bluez-libs: 5.50-7
gst-plugin-pipewire: 1:0.3.20-1
alsa-card-profiles: 1:0.3.20-1

Not sure if all of these are relevant, but I'll try to incrementally upgrade and see what happens.

Update: I've upgraded the pipewire and bluez packages to their current repo versions, and have gone the day without disconnecting.

Update 2: I've upgraded everything but linux-firmware to their current repo versions and have been using my headphones flawlessly for over 5 hours so far.

i've tried with the new pipewire 0.3.22-1 and another bluetooth speaker, same random disconnects.

Journal with disconnect message, pretty much the same as others:

Feb 20 19:47:54 lenovo dbus-daemon[626]: [system] Rejected send message, 0 matched rules; type="method_return", sender=":1.55" (uid=1000 pid=1711 comm="/usr/bin/pulseaudio --daemonize=no --log-target=jo") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.14" (uid=0 pid=727 comm="/usr/lib/bluetooth/bluetoothd ")

I'm wondering if anyone knows what this message is actually telling us?

What did I try?

* I think I ruled out pulse as part of the problem by playing internet radio with

 mpv --ao=alsa

-> same disconnects

* I disabled GDM and am starting xfce through Xinit -> this seems to help. I have to check on timings for disconnects. It happened about every 15 minutes and that's much better now
* I'm using the LTS kernel and sometimes switch to regular, with no noticeable difference
* I' m using Audacious now instead of MPD with a bigger than standard buffersize and started from CLI with

 audacious -V

-> have to check this beter than I did 'till now

[EDIT]

There has indeed been some changes regarding bluetooth with the 08-02 linux-firmware for the AX200 chip as stated above. It's kind of safe to assume that that would give us the issues. Reading the posts above a bit better now, all other possible causes are too diverse, I feel. I' m actually not sure how to address this (bug report), anyone does?

As an update...since both Linux and bluez updated recently, I went ahead and updated linux-firmware. No disconnects so far, so that may have been a red herring.

Megarock90 · 2021-02-26 05:48:43

Same symptoms on the same AX200 board with some Avantree headphones. Downgrading the firmware package to 20201218 helped.

I'm also having this issue with an AX200, and it just started within the past few weeks. I downgraded linux-firmware (20201218.646f159-1) but it did not fix the issue.

My journalctl output looks similar to others also.

I had the same issue beginning with the latest full system upgrade. I downgraded both linux and linux-firmware and it resolved the issue for me so far. I went to version

linux-firmware-20201218.646f159-1
linux-5.10.12.arch1-1

edit: It looks like only linux-firmware needed to be downgraded. No reason to downgrade the kernel as well.

So after reading https://bbs.archlinux.org/viewtopic.php?id=264066 and updating the kernel to 5.11.2 (zen build) I decided to try and upgrade the firmware as well.
I'm currently into about 2 hours of uninterrupted playback.

Edit:
Aaaaand just happened again. Unrelated from the kernel then, downgrading the firmware again.

I'm so glad I've found this thread. I only use my bluetooth earbuds sparingly but noticed throughout the last couple weeks that my earbuds would randomly disconnect (multiple times a day).

After having downgraded the linux-firmware package to the previous version (20201218.646f159-1) I haven't had any issues since -- (Lenovo T14s with Intel AX201 chipset for bluetooth).

Not sure yet where to report linux-firmware bugs. Also not sure I have enough for a bug report ?

tombh · 2021-03-04 01:31:39

Unfortunately I've not had success with the downgrade to linux-firmware (20201218.646f159-1), I'm on a Dell XPS 13 from 2020, chipset is AX1650i. Though I'm still on the latest kernel 5.11.2.arch1-1

For the past few days I've been on linux-lts kernel 5.10.19-1-lts and linux-firmware 20201218.646f159-1 and I've only had 1 disconnect. I tried the newest version of linux-firmware and my bluetooth speakers wouldn't connect at all so I downgraded again.

4johnny · 2021-03-05 15:27:49

I've downgraded my system by following the arch wiki archive guide: https://wiki.archlinux.org/index.php/Ar … cific_date
My mirrorlist file now looks like this (Note: I also had to disable signature checking: https://wiki.archlinux.org/index.php/Pa … _checking):

/etc/pacman.d/mirrorlist

Server=https://archive.archlinux.org/repos/2020/12/16/$repo/os/$arch

Note the date I've used is set to "2020/12/16", I previously tried setting it to "2020/12/31" but that didn't solve the issue for me, though it seemed to happen less often... (I suspect that version 20201218... already contained the issue?)!
My linux packages are now the following:

local/linux 5.9.14.arch1-1
    The Linux kernel and modules
local/linux-api-headers 5.8-1
    Kernel headers sanitized for use in userspace
local/linux-firmware 20201120.bc9cd0b-1
    Firmware files for Linux
local/linux-headers 5.9.14.arch1-1
    Headers and scripts for building modules for the Linux kernel
local/linux-lts-headers 5.4.83-1
    Headers and scripts for building modules for the LTS Linux kernel

I did this action 3-4 days ago and haven't had a disconnect since.

Downgrading to linux-firmware 20201218.r1803.646f159-1 did not fix the issue for me. Using an AX200 Wifi Card with bluetooth and wireless bluetooth headphones.
