Re: Random bluetooth speaker disconnects

OP here. I followed the vast replies in this thread (thank you all for that) and tried all of the mentioned methods and workarounds. None of them helped me, with my hardware. Yesterday I switched from pulseaudio to pipewire and finally the random disconnects stopped happening.

Re: Random bluetooth speaker disconnects

Can confirm after a hard reboot that the new firmware fixes the issue with pipewire and my WH-1000XM4's!

Re: Random bluetooth speaker disconnects

After latest firmware released in the past days seems fixed on my laptop, AX200 card showing the following in dmesg:

$ sudo dmesg | grep 'Bluetooth: hci' | grep 'Firmware revision'
[   15.463274] Bluetooth: hci0: Firmware revision 0.0 build 118 week 15 2021

Firmware version:

$ pacman -Ss linux-firmware
core/linux-firmware 20210426.fa0efef-1 [installed]
    Firmware files for Linux

I needed to do a shutdown of the laptop for the firmware to be loaded into the card.

Re: Random bluetooth speaker disconnects

Hi, I am having the linux-firmware-20210426.fa0efef-1 installed but it is still loading the old firmware. I have restarted and shutdown the system multiple times since the upgrade.

$ pacman -Ss linux-firmware
core/linux-firmware 20210426.fa0efef-1 [installed]
Firmware files for Linux
 
sudo dmesg | grep 'Bluetooth: hci' | grep 'Firmware revision'
[sudo] password for power: 
[    3.208869] Bluetooth: hci0: Firmware revision 0.0 build 121 week 7 2021

Any suggestion how to "force" load the new firmware?  It is present on the filesystem:

ll /usr/lib/firmware/intel/ibt-20-*
-rw-r--r-- 1 root root    9 Apr 28 09:31 /usr/lib/firmware/intel/ibt-20-0-3.ddc
-rw-r--r-- 1 root root 765K Apr 28 09:31 /usr/lib/firmware/intel/ibt-20-0-3.sfi
-rw-r--r-- 1 root root    9 Apr 28 09:31 /usr/lib/firmware/intel/ibt-20-1-3.ddc
-rw-r--r-- 1 root root 767K Apr 28 09:31 /usr/lib/firmware/intel/ibt-20-1-3.sfi
-rw-r--r-- 1 root root    9 Apr 28 09:31 /usr/lib/firmware/intel/ibt-20-1-4.ddc
-rw-r--r-- 1 root root 765K Apr 28 09:31 /usr/lib/firmware/intel/ibt-20-1-4.sfi

Thanks.
