Issue:
I have installed cadmus using the .deb package on linuxmint 20.2. Upon starting the application and selecting the mic input from the menu, the denoise virtual device fails to get created. It's not seen in the PulseAudio input device list. Trying to start the device from the command line and performing the same action of adding the mic device in strace mode, below error could be noted:

This consistently happens even after trying to restart the application.

System details:
Linux Mint 20.2 x86_64
Desktop env: Cinnamon
Hardware: ThinkPad T580

Additional note:

  • When the app gets launched, its visible in the panel tray. But in the app menu, the suppression slider seems missing. At the time of failure, If trying to switch to another mic input source, it generates the below error:

  • In a very random way, the denoise device gets created sometimes, and the device appears to work until the laptop is restarted.
