Description Rasmus 2023-03-13 11:30:48 UTC

SUMMARY
When using Elisa and changing the volume using the built-in volume slider, the actual audio volume lacks behind the slider change by like 1–2 seconds. So, when using the slider to change the volume, it takes 1–2 seconds to take effect instead of taking effect instantly.


STEPS TO REPRODUCE
1. Open Elisa
2. Play any music
3. Change the volume using the built-in slider

OBSERVED RESULT
Audio volume takes a couple seconds to take effect.

EXPECTED RESULT
Audio volume should take effect instantly

Can reproduce on Fedora KDE 37 with PipeWire and Wayland.

Comment 2 Rasmus 2023-03-14 11:14:04 UTC

Also happens in JUK music player

Comment 3 Nate Graham 2023-03-14 15:21:45 UTC

Interesting. That suggests this is an issue in PipeWire deeper than either of these apps. Can you submit a new bug report at https://gitlab.freedesktop.org/pipewire/pipewire/-/issues? Thanks!

Also seems to happen on VLC, so that may be the case. Will submit a bug report

Comment 5 Nate Graham 2023-03-14 16:10:14 UTC

Elisa uses VLC for playback; dunno about JuK. If JuK does too, it could indeed be a LibVLC issue.
