Well it's pretty much in the title.
I did the Update to Ubuntu 18.04 with the update manager. However, now when I select several files in the file manager and hit enter, only the last in the list gets opened and played by Audacious.
Apparently, my system behaves a bit weird. Three options to open multiple sound files
- Selecting them in the file manager, hit enter
- Selecting them, right click and click on Open with Audacious
- Selecting them, right click, go to sub-menu Open with ..., and then selecting Audacious
Only when I do it following the steps listed in the last point, then Audacious opens all files and puts them in a list.
