[Feature request] How to change the audio read source

[CmsMartin]

Now my audio is taken from microphone by default. And I don't have a way to change which sound gets from the system. Changing the data source to PulseAudio will not change the frequency spectrum above. I want to know how can I fix it.

I think this is a duplicate of #112.

BTW regarding the PulseAudio backend there is a bug with some python files that is fixed but still present in the latest release in ~/.local/share/plasma/plasmoids/panon/contents/scripts/soundcard
After you install the dependencies and the plasmoid you can run sed -i 's/collections.Iterable/collections.abc.Iterable/g' ~/.local/share/plasma/plasmoids/panon/contents/scripts/soundcard/*.py to fix it.
