Tixati is opening audio files in Audacity despite applications such as mpv, smplayer and clementine installed in the system. Video files are rightly opened in mpv though.

There are no associations set between Audacity and audio files in .config/xdg-mimeapps-list. In fact, the default applications in that config file are clementine and mpv.

See the commands used in this thread: https://forum.tixati.com/support/7070
xdg-mine query, xdg-open, xdg-mime default. What do they report and does setting anything manually there help? What about setting defaults in system settings?

$ xdg-mime query default audio/mpeg

and

$ xdg-mime default mpv.desktop audio/flac

returned

audacity.desktop

Changed them to mpv.desktop.

$ xdg-mime default mpv.desktop audio/flac
$ xdg-mime default mpv.desktop audio/mpeg

Works fine now. Thanks a lot for your reply.
