Describe the bug Panon was working fine for a few days. Recently when I rebooted the system, the widget is showing: Failed to load the visual effect. Please choose another effect in the configuration file.

I do not see any input device in the back-end when I select PulseAudio. It only shows 01 device named "default". Also, I followed steps to remove NewStuff, restarted and nothing worked.

I love Panon and hoping the issue gets resolved soon.

Ran in to this issue today, solved it by installing the needed python dependencies. sudo apt install python3-docopt sudo apt install python3-websockets sudo apt install python3-pyaudio
