whenever I want to play some music files with Audacious (adding them via Nemo via right click => play in Audacious) there is a lag of about 5-10 seconds where the desktop isn’t responding at all. After this few seconds the notification of the played song appear and the desktop is responsible again.
I accidentally took a laptop on the coach with me for 3 hours, one with ‘an ubuntu’ on it, got the music out, sadly, forgot to sudo apt purge rhythmb* and install deadbeef, so had to waste laptop and phone battery getting internet hotspot phone turned on to allow installation of chrome to allow dl of deadbeef.
Thereafter could listen to what I wanted without a ‘music player’ messing up it’s ONE JOB by trying to be a notifying and playlist building crumpet.
Uninstall Audacious, or never start it. Both solutions work for me.
