Bug ID: 524376
Summary: Audio controls can get "stuck" when using Bluetooth
audio
Classification: Plasma
Product: plasmashell
Version First 6.6.6
Reported In:
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Audio in general
Assignee: [email protected]
Reporter: [email protected]

Target Milestone: 1.0
DESCRIPTION
The volume controls occasionally get "stuck" when using Bluetooth audio.
Attempting to change system volume using keyboard shortcuts only allows
changing volume within a very narrow range (for instance, 57% - 67%, you can't
go lower than the lower bound or higher than the upper bound). Attempting to
change system volume using the volume widget in the panel "works" in that you
can hear the volume change, but the slider snaps back to its original value
when you let it go even though the volume change persists. Changing system
volume using buttons on the Bluetooth device itself "works" in that you can
hear the volume change, but Plasma usually does not show the volume change in
the volume widget.
STEPS TO REPRODUCE
1. Grab a pair of Bluetooth headphones (I'm using some relatively cheap JLab
Studio 2 headphones).
2. Pair them to the system like you would any other Bluetooth device.
3. Once paired, play a song on YouTube and ensure you can hear audio out the
headphones.
4. Close the YouTube browser tab completely (do not just pause the video).
5. Open the Bluetooth widget, and disconnect the headphones.
6. Open a new YouTube tab, and start a song playing.
7. While audio is playing out the system speakers, reconnect the Bluetooth
headphones.
8. After reconnection, restart the song playing if your browser automatically
paused it.
9. While audio is playing out the Bluetooth headphones, attempt to change
system volume.
10. If the volume controls are "stuck" as described above, skip to step 13.
11. If the volume controls are not "stuck", disconnect the Bluetooth headphones
while audio is still playing, restart the song if the browser automatically
paused it, reconnect the headphones, and restart the song again if the browser
automatically paused it.
12. Repeat steps 9 through 11 until the audio controls get "stuck".
13. Once the audio controls are stuck, close the YouTube tab. The audio
controls should become unstuck.
OBSERVED RESULT
Audio controls can get stuck.
EXPECTED RESULT
Audio controls do not get stuck under any circumstance.
SOFTWARE/OS VERSIONS
Operating System: Kubuntu 26.04 LTS
KDE Plasma Version: 6.6.6
KDE Frameworks Version: 6.24.0
Qt Version: 6.10.2
ADDITIONAL INFORMATION
This bug doesn't only occur when connecting headphones while audio is actively
playing. Sometimes audio controls won't be stuck, but then at some random point
they will become stuck (this may be related to audio streams stopping and
starting, which happens on my system a lot since I listen to a lot of music).
Connecting headphones while audio is actively playing seems to be the easiest
way to reproduce the issue quickly though.
This issue may be hardware-dependent. My system (a Kubuntu Focus M2 GEN 5) is
using an Intel AX211 chip for WiFi and Bluetooth, and as mentioned above, I'm
using JLab Studio 2 headphones. I do not know if this bug can be reproduced
when using other Bluetooth chips or headphones.
