So I have been running into a weird issue lately where if I disconnect a Bluetooth audio device, it will remain visible in the KDE audio mixer. Reconnecting the audio device then adds a duplicate entry and the keyboard volume control for it is completely broken. It stays at the same volume. This was working just fine about a week ago and I've already downgraded pipewire, kpipewire, bluedevil, and plasma-pa to no avail. Nothing shows up in the logs, so I don't know exactly what's causing this bug.
Anyone else experiencing the same thing?
Arch Linux
Kernel 6.4.8-arch1-1
Pipewire 0.3.77-1
KDE Plasma: 5.27.7
KDE Frameworks Version: 5.108.0
Qt 5.15.10
EDIT: Seems like simply changing the Bluetooth A2DP audio profile causes this issue as well. I have Bluetooth earbuds that have both AAC and SBC modes and toggling between them just creates more and more duplicate devices with the same name.
THE FIX: Seems like pipewire-pulse 0.3.77 was the culprit after all. Downgrade it to pipewire-pulse 0.3.76 and then do a systemctl --user restart pipewire-pulse to workaround this issue.
EDIT 2: pipewire-pulse 0.3.77-2 has the patch backported. Feel free to update to latest version in Arch repos.

This doesn't seem to happen to me. Are you using pipewire by any chance?
Yes. I found the issue. Seems like there's a regression in
pipewire-pulse0.3.77. Thanks for helping test anyways :)Thanks for this - I have been seeing the same symptoms with connecting/disconnecting USB audio devices on a brand new (<24 hours old) Endeavour install. I'll check pipewire version in the AM.
Np! It's already fixed upstream by the way. It's a super small patch so it was easy enough to download the pipewire-pulse PKGBUILD and patch the package myself.
