Comment 1 Rex Dieter 2016-08-24 17:55:37 UTC 
confirmed (plasma-5.7.3/fedora-24)
Comment 2 Trent Reed 2016-09-05 20:22:38 UTC 
Also running into this on KaOS (plasma-5.7.4/KaOS)
This issue can be found in both the system settings and the plasma-pa applet.

Slightly more information: KaOS uses phonon-gstreamer backend.
Comment 4 Pavel 2016-12-14 21:20:29 UTC 
Have the same issue. System notification sound is too loud and I can't change it volume.
OS: OpenSUSE Thumbleweed x64, Plasma 5.8.4
Comment 5 Timo Kalliomäki 2017-04-10 09:16:19 UTC 
Notification volume being stuck to zero is also present on Debian Stretch, Plasma 5.8.6
Comment 6 Nate Graham 2017-04-28 16:39:43 UTC 
Still a problem with Plasma 5.9.4 on openSUSE Tumbleweed.
Comment 7 Orbmiser 2017-04-28 16:48:41 UTC 
Yep same issue ongoing Plasma 5.9.5 here on Manjaro Arch based.
Also missing popping sound on mouse wheel volume change. 
Use to be there and other notifications sounds work.
Comment 8 Nate Graham 2017-04-29 00:11:11 UTC 
A workaround has been discovered: install the `pavucontrol` package and use `/usr/bin/pavucontrol` to adjust the notification volume. This change becomes "sticky" such that uninstalling pavucontrol along with its deps restores the notification sound slider's adjust-ability as well as bringing back system sounds if they were totally gone for you (https://bugs.kde.org/show_bug.cgi?id=379316).

Prevent unnecessary setting mute

Can someone please test this patch on Plasma 5.9.3 and newer?
Comment 10 demm 2017-04-29 15:16:16 UTC 
Using the above patch on plasma-pa 5.9.5 fixes the issue in KaOS. (Frameworks 5.33.0, Qt 5.8.0).

Git commit b364a9e6c60cd3681ee7f3680179251e2efd2939 by David Rosca.
Committed on 29/04/2017 at 21:00.
Pushed by drosca into branch 'master'.

StreamRestore: Don't write unnecessary changes

Applet updates mute state with every volume change - it does
writeChanges(volume) immediately following with writeChanges(mute)
and it seems to make PulseAudio to ignore the volume change.
This makes sure that writeChanges() is only called when something really
changed.
FIXED-IN: 5.10.0

Comment 13 Darin Miller 2017-09-23 14:05:41 UTC 
This problem is still present in Kubuntu 17.10 with plasma 5.10.3 and 5.10.95.
Comment 14 David Rosca 2017-09-24 10:24:01 UTC 
Another change will be in 5.11 that should finally fix this issue.
Comment 15 Nate Graham 2017-09-24 13:50:53 UTC 
Can you point folks to a commit or Phabricator revision for that change?

Thanks David! And let's always try to mark duplicate reports as such and consolidate information in the master bug. That way interested parties have one central place to find the bug's status, and it's also easy to gauge the level of interest (10 dupes on one bug says more than 10 discrete bugs that haven't been marked as duplicates).

Comment 21 Mark Smith 2019-08-01 23:23:57 UTC 
I had this bug on the latest KDE Neon (5.16). Took me a few hours to find out this solution of installing pavucontrol to unstick the volume mute/zero for system notification sounds. Also, I think this caused an annoying delay in displaying of any notification that also had a sound, for example, it would take like two seconds to display the volume change popup when changing the volume, or when it displays confirmation popups.
