I am using Rawtherapee 5.8 Appimage on Ubuntu 18.04.
The “sounds” emitted by RT after editor processing or queue processing are not working.
Here is what I checked :
The sound tab of preferences is enabled. I tried testing the default sound options like "window-attention’ on command line (canberra-gtk-play -i window-attention). They work. So probably nothing wrong with OS sounds. Also tested with diff values of cut off period in seconds. The “options” file being accessed is the correct one.
I remember that the sounds were working when I was using an earlier RT version from Ubuntu repository. Though had the same issue with RT (flatpak). So looks like some kind of integration issue between Ubuntu and the appimage.
