I can't reproduce this here at all, might be specific to your installation.

Comment 2 robert marshall 2021-09-15 14:55:08 UTC

I'm seeing this sometimes too - but I'm not sure what is provoking it - or how to reliably show the bug.

Comment 3 Myriam Schweingruber 2021-09-17 08:13:29 UTC

Reopening based on Roberts comment

Comment 4 Tuomas Nurmi 2024-05-26 20:40:02 UTC

Based on discussion and extra information on mailing list, I managed to reproduce at least one case where this happens:
With Phonon VLC backend, if a playing track is stopped, master volume is set to 0. Playback will continue with correct volume if a next track is played. However, if Amarok is shut down with playback stopped, the 0 gets written as the master volume setting and will be the initial volume on next startup. Will create a fix MR shortly.

Pushed by nurmi into branch 'master'.

Avoid volume getting set to 0 when phonon-vlc playback is stopped

Shouldn't affect behaviour with other backend(s), which do not experience the
bug.
