[SOLVED] Bluetooth not working after system update

carmik · 2025-10-17 07:11:45

Got some bluetooth headphones that were operating fine on KDE Arch (standard Linux kernel). Tried to listen some music yesterday and even though I could pair with them just fine, there was no bluetooth output on the KDE sound applet.

Sound to other wired devices works just fine, as well as a microphone.

Any idea what to look for?

As a first guess, do the versions reported by uname -a and by pacman -Q linux (assuming you are using the stock kernel) match?

Look good AFAIK:

$ pacman -Q linux
linux 6.17.2.arch1-1
$ uname -a
Linux shocknawe 6.17.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Sun, 12 Oct 2025 12:45:18 +0000 x86_64 GNU/Linux

I have same issue: bluetooth connects, device appears and I can see sink but no sound coming out.
I do not use KDE though, I'm on hyprland with some remains of gnome-desktop from which I switched to hyprland.

Couple months back bluetooth worked just fine. I did not change any configuration, only thing I did consistently - `pacman -Suuy`.
I did not need bluetooth for the last several weeks so I'm not sure after what update it stopped to work.

I tried rolling back many packages: linux, bluez, linux-firmware, etc. Nothing helped.

My current versions (with rolled back bluez, linux & linux-firmware):

$ pacman -Q --info linux bluez pipewire wireplumber linux-firmware linux-firmware-intel | grep -B 1 Version

--

Version         : 20250627-1

After downgrading firmware, I did proper power-reset (with disconnecting from power socket) to force firmware refresh.

Seems to be a recent issue. Checking my pacman log:

This is a new arch installation (couple of months). It did work in September. Something to do with the bluez-qt upgrade? Wish we could correlate the date the issue started with the upgrades done. Unfortunately I mostly use wired headphones, so I can not tell when the issue actually appeared.

Found out that replacing wireplumber with pipewire-media-session makes bluetooth work.
Though rolling back wireplumber to 0.5.11-1 did not help

carmik · 2025-10-21 18:11:12

pipewire-media-session is supposed to be replaced by wireplumber, so that's no go for me... Thankfully main headset is wired, so no biggie atm.

seth · 2025-10-21 20:45:23

Have you already tried to https://wiki.archlinux.org/title/WirePl … t_settings ?

carmik · 2025-10-22 16:27:34

Tried that, same result. In KDE headphones seem connected over bluetooth. wpcli status does not show the device, bluetoothctl shows it as connected.

seth · 2025-10-23 07:29:27

Please post your complete system journal for the boot after running wpcli status

sudo journalctl -b | curl -F 'file=@-' 0x0.st

carmik · 2025-10-23 17:58:34

Today it works just fine!

For the record, this is a combined wpctl status / dmesg log before pairing the headphones: http://0x0.st/K2Pt.txt

And this is after: http://0x0.st/K2Pt.txt

From pacman log I can see that from the day I had this issue, there has been no changes related to pipewire/bluetooth, but the kernel has been updated. The packages that got updated during this time: http://0x0.st/K2P3.txt
