Description svoboda 2025-12-05 09:00:26 UTC
SUMMARY
Stutters at the beginning of every track. I like the design but this makes it unusable for me. I have my music collection on a permanently mounted Windows partition. If this would be the reason: No excuse, all other players I tried play my songs without a flaw: VLC, Amarok, Strawberry, Rhythmbox. Tried to use Elisa for months, so updates came through, but didn't help with the stuttering.

Are you by any chance streaming the audio over Bluetooth?

Hi Nate,

yes, I'm streaming over Bluetooth - which works fine with other apps.

And it doesn't happen when the output is a non-Bluetooth local speaker or headphones, right?

Hi Nate,

I cannot say wether it works without stutter over the notebook speakers. 
I had uninstalled Elisa, annoyed by the bug. No I have reinstalled it 
though not the flatpak but the dnf version instead. And it doesn't 
stutter over bluetooth! Seems to be an issue in the flatpak package. BTW 
the other apps I tried like Strawberry are flatpaks and work well with 
bluetooth.

Cheers

Markus

Yep, a colleague of mine confirmed the same thing. Seems to be Flatpak-related indeed.

I can reproduce it with the version on Flathub as well as the version in the KDE nightly Flatpak repo.

The Fedora Flatpak version is fine, interestingly.

A difference is that the Fedora Flatpak version uses the QtMultimedia backend with its own GStreamer backend, while the Flathub/Nightly builds use the LibVLC backend with its own ffmpeg backend.
