Thanks for the bug report. Please check to see if you have 'timidity' or 'pipewire' packages installed as either of those can cause such a problem. If you don't know how, then just run this command in a Terminal:

  dpkg -l > packages.txt

and attach the resulting text file here.

Hello Daniel,

Packages named 'timidity' or 'pipewire' are not installed. File packages.txt in attachment.

Regards, Dmitriy.
