Title:
Changing sound left/right balance impacts on front/back
Status in gnome-control-center package in Ubuntu:
New
Status in pulseaudio package in Ubuntu:
Triaged
Bug description:
What happens:
If an Asus STXII 7.1 sound card is installed and another output device
is present, there is a strange behavior in the Gnome audio settings.
After the first start of Ubuntu the Asus soundcard is not the default
device. This can be selected in the Gnome settings. If a different
speaker configuration is selected now. E.g. stereo instead of 5.1 or
vice versa, the selection jumps from the Asus output device back to
the original output device. The Asus sound card can then be selected
again and the corresponding speaker configuration will fit now.
If 5.1 is selected as the mode, there is a second problem.
Moving the balance slider (left / right) moves the slider (front / back)
slightly as well.
The slider for lfe is grayed out, even when I enable the lfe remixing in
/etc/pulse/daemon.conf
In the speaker test, all 5.1 channels work fine, including the lfe.
For better illustration I made a screen video. (see attachment)
This is probably a general bug in Gnome - it has been occurring since
Ubuntu 18.x and affects all distros that use Gnome since then.
Unfortunately I was not able to make a report in Gnome, because the
registration on the Gnome site does not work anymore... Maybe you have
a good contact to the Gnome team?
Ubuntu 20.04 LTS (Release 20.04)
Package: gnome-control-center (1:3.36.1-1ubuntu5)
Expected behavior:
It should be possible to select the sound card and the setting should be
retained even if the speaker configuration is changed. Furthermore, the balance
sliders should not influence each other.
Lfe slider should work. (And in a perfect world this would also activate lfe
remixing and gives the user a cross over frequency option, but this is just an
idea :)
BR,
Mathias
