Title:
Microphone is silent if left and right channels are set to the same
volume
Status in linux package in Ubuntu:
Confirmed
Bug description:
If the microphone volume is set the same for both left and right
channels, it's nearly silent, being unusable, as if the left and right
channel cancel each other.
The workaround I had on Focal was to create a remapped source only
with the right channel. However, on jammy, another bug makes this
workaround fail.
While I reported the pipewire bug at
https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1734 I'm
also reporting this bug so, hopefully, the kernel could be fixed and
no workaround would be required in the future.
The following image shows an example of the volume disparity that
makes the microphone work properly:

While such setting allow to use the microphone, it's annoying for the
people I'm talking with.
