Notification sounds where always 0 or muted on this machine. I want to use them now. Increasing the volume slider of the notifications inside system settings makes the slider jump back to zero all the time. In that event no error is displayed and no error is printed in console. However, on loading of the module, there are quite some errors in the console. None of which showed a solution during research: Errors: https://pastebin.com/RzHjpd5v
I experienced the same. Notification sounds immediately mute themselves against after touching the slider.
Update: I could fix the behavior with pavucontrol. When opening it, it showed "Notifications" muted. I unmuted it and raised the volume. Notification sounds now play and I can adjust the volume both from, systemsettings and pavucontrol. I have no idea why systemsettings was not able to alter the volume values and pavucontrol could.
This should have been already fixed, see bug 367688. I can't myself reproduce it.
I reproduced it on Plasm 5.10.4, though. I'm also seeing the same issue with neon dev edition git master of a couple of days old.
Created attachment 107423 [details] debug Can you apply this patch and send me the output when changing the volume?
I confirm this bug on neon dev unstable.
I unmuted, after that I moved the slider to 40%: set volume 39637 write changes 0 false "" set muted false set volume 0 write changes 0 false "" set muted true write changes 0 true "" set muted true As you can see it sets volume to 0 again afterwards.
