[BUG] Panon visualizer doesn't react to audio

Desktop

• OS: Arch Linux
• KDE Frameworks Version: 5.91.0

Describe the bug
No matter what audio I play, Panon doesn't react to playing audio, it just stays flat. Tried all audio backends and multiple styles.

Any error message shown in the console

Installed both through ocs-url and AUR, both had same issue.

I got some error in my OS

Edit: The solution here fixed the problem for me - #78 (comment)

I have the same error on both Arch and EndeavourOS.
When I was on Kubuntu or Debian, Panon worked appropriately.

I'm not sure what the difference is, I've confirmed I have all required dependencies. Similar to OP, I've tried all backends and input settings. I've also tried with both pipewire-pulse and with standard pulseaudio installed, and there is also no difference between X11 and Wayland environments.

@ViejoRS Same error here in Arch recent install

Yes, I am meeting a similar problem like this. Actually when I change the audio data source to "PortAudio", panon works properly and it catches my microphone signals and make them visual. When I change the audio data source to "PulseAudio" and it doesnt work properly in every mode.

Arch 6.1.9 with KDE Plasma 5.26.5, X11.

The same problem on Ubuntu 23.04, it uses pipewire-pulse and with "PortAudio" panon shows only microphone signal, not the speakers signal, and I see no ways to choose the input channel manually.

I've created a feature request about this: #112
