Bug ID: 400789
Summary: plasma-pa does not change the volume on the default
pulseaudio sink when audio is reproduced
Product: plasma-pa
Version: 5.14.2
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: applet
Assignee: now...@gmail.com
Reporter: giuseppemargar...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: ---
SUMMARY
When you change the default pulseudio sink from the one of your sound card to
another (maybe the equalizer or PulseEffetcs), pulseaudio won't control the
volume of the default sink when audio is playing.
It only controls the default sink when no audio is playing.
STEPS TO REPRODUCE
1. You have a pulseaudio sink, let's call it "Stereo Internal Audio", linked to
your sound card and it's the default after a fresh install.
2. Make a new pulseaudio sink, i.e. using PulseEffects, and let's make it the
default sink.
3. Change the volume through keyboard key and PulseEffects default sink is
affected correctly.
4. Let's start a song or a video file and you make sure that the default
PulseEffects sink is used by the application.
5. Change the volume and you will see that PulseEffetcs sink IS NOT affected by
plasma-pa. Volume is changed on the sound card sink: Stereo Internal Audio. You
can also notice that nothing is changed in pulseaudio configuration:
PulseEffects is still the default sink.
6. Stop the reproduction, close the mediaplayer application and change the
volume again. PulseEffects is affected.
OBSERVED RESULT
plasma-pa does not respect the control on the default sink when an audio stream
is reproduced.
EXPECTED RESULT
plasma-pa should always change the volume on the default sink, or at least it
should let you choose the preferred sink to control even if it's not the
default in the pulseaudio config, just like it's done in kmix.
SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version: 5.14.3
KDE Frameworks Version: 5.51.0
Qt Version: 5.11.2
ADDITIONAL INFORMATION
kmix is another volume manager and it lets you choose one sink to control and
volume control always affects that sink even if it's not the default sink.
While the behavior in plasma-pa is clearly a bug because considering that:
- It does not let you choose a preferred sink to control;
- It lets you switch the default pulseaudio sink changing the pulseaudio
configuration and the sink to be used by all applications
When you set a default sink different from the one associated to the sound card
and reproduce something, it won't control the volume on default sink.
