So I use Fedora with ffmpeg-free and the AMD drivers swapped out with the RPM fusion versions. My default mp4-player is Firefox so I never had any issues but for academic reasons I decided to test Elisa.
No sound plays.
I enable my built-in speakers, the sound plays through them.
I try Dragon Player, same issue.
I google it, no solution.
I ask AI, still no solution.
I uninstall both of them and swap to Firefox, problem solved.
Installed mpv (flatpak) just to check, works fine (other than the media controls being tiny and there being no settings menu).
So my question is, is this a normal thing for KDE or is this a Fedora thing? I tried various steps but nothing seemed to work. Apparently others have solved this with different media players (like I have), and apparently in the past Fedora lacked mp3 support (but not currently).
I need to know if I can blame KDE for this and thus recommend Fedora, or whether this is a Fedora issue.
EDIT: I reinstalled them as flatpaks and they're fixed. I would still ideally like to know why they refuse to use the selected bluetooth headphones and instead use the speakers.
EDIT 2: I installed Elisa on my CachyOS desktop that doesn't have built-in speakers and it played through Bluetooth properly. Next I'll need to liveboot into Kubuntu or something and see if the issue persists.
