Bug ID: 464192
Summary: Opening the PulseAudio applet automatically changes
bluetooth headset to headset mode
Classification: Plasma
Product: pulseaudio-qt
Version: 1.0.0
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: nicolas.fe...@gmx.de
Reporter: zsolt.do...@tutanota.com
Target Milestone: ---
SUMMARY
***
When clicking on the PulseAudio applet in the task bar while listening to music
on my bluetooth headsets, the applet starts listening to the headset's
microphone and thus changes it to "headset" mode (mSBC), which is terrible for
music (it has a much louder profile, bad audio quality, and is in mono). This
makes it very impractical to use the applet to change volume, or do any other
changes while listening to music. I suspect the applet listens to music to show
a volume bar (which is a nice idea but has this unfortunate side-effect). After
the applet stops listening to the microphone, my headset would automatically
switch back to high-quality headphones mode (A2DP).
I own a Plantronics BT600 headset which I use with its USB dongle, and thus I
am not connecting it directly to my computer through bluetooth, so no
PulseAudio/PipeWire/WirePlumber is involved in this switching. I believe this
is pretty common practice amongst similar headsets.
STEPS TO REPRODUCE
1. Connect some bluetooth headset that behaves as explained above
2. Start listening to music
3. Click on the PulseAudio applet with the intention of changing the volume
OBSERVED RESULT
Now your ears are blasted with loud, bad quality music, which will stay like
that for something like 5 seconds after closing the applet.
EXPECTED RESULT
Clicking on the applet should not trigger my headset to switch to "headset"
mode.
Maybe have an option in the applet's settings to control whether one wants to
see the microphone volume?
Note that "Audio" under System Settings does not have this issue, even though
it offers a pretty similar feature set to the applet (because it does not try
to show the microphone volume).
