Elisa-git (2019-04-14) music playback stutters STEPS TO REPRODUCE 1. Compile Elisa from git 2. Import library OBSERVED RESULT Music playback stutters EXPECTED RESULT Music is played fine SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.15.4 KDE Frameworks Version: 5.57.0 Qt Version: 5.13.0 Kernel Version: 5.0.7-arch1-1-ARCH OS Type: 64-bit Processors: 16 × AMD Ryzen 7 1700 Eight-Core Processor Memory: 31,4 GiB of RAM
Cannot reproduce with the following software & hardware FWIW: Operating System: Manjaro Linux KDE Plasma Version: 5.15.3 KDE Frameworks Version: 5.56.0 (or git master) Qt Version: 5.12.2 Kernel Version: 4.19.32-1-MANJARO OS Type: 64-bit Processors: 4 × Intel® Core™ i7-7500U CPU @ 2.70GHz Memory: 7.7 GiB of RAM Notable differences are that the reporter is using a newer Qt and Kernel.
Now using Qt 5.13 and still cannot reproduce.
elisa-git will stutter on playback if it is compiled with the VLC backend and a networked Pulseaudio setup is used. It can be worked around compile-time by simply not having libblc installed - which makes Elisa "fall back" to QtMultimedia - which seems to work just fine. VLC has the exact same problem if it's playing to a local PulseAudio instance which has a remote sink on another machine as output. It's 100% reproducible in both elisa (when compiled with libvlc) and VLC. This bug can simply be closed if Rainer Finke is using a similar setup and Elisa is/was compiled against libvlc.

Thanks a lot for the information. Did you already reported it to VLC project ?
Rainier, were you using a networked pulseaudio and/or the VLC backend?
Nate, I remember that I've used the vlc backend in the past, but not exactly when I switched to gstreamer to use pipewire on Wayland. So I can only assume that this might have been the issue. Just now I've compiled Elisa-git and playback was fine. I propose to close this bug.
