same problem on plasma 5.16 beta.

Operating System: Arch Linux 
KDE Plasma Version: 5.15.90
KDE Frameworks Version: 5.58.0
Qt Version: 5.13.0 beta3

Cannot reproduce. It looks from your video like mute mode is being reset to on no matter what volume you set. That's odd. Does it work if you first uncheck the mute button on the right?

No. It's still reproducible on my neon dev unstable.

Very strange.

The same problem occurs with Plasma 5.15.5 on Arch Linux.
Operating System: Arch Linux 
KDE Plasma Version: 5.15.5
KDE Frameworks Version: 5.58.0
Qt Version: 5.12.3

I just noticed that the slider indicates the volume level incorrectly on Plasma 5.16 beta. As we can see in the attached screen recording, 100% is positioned in the left side of the slider, 0% is positioned in the right side.

I have the problem, too.

If i change notification sounds volume, it gets muted/set to zero.

Operating System: openSUSE Tumbleweed 20190612
KDE Plasma Version: 5.16.0
KDE Frameworks Version: 5.58.0

Could this bug be related to the fix for bug 398392 ?

since you are considering my bug report a duplicate of this one i'm copying my post here.

please review the following threads. the notification sounds cannot be enabled. i'm assuming it's a plasma desktop issue.

https://www.linuxquestions.org/questions/linux-general-1/no-notification-sounds-in-kubuntu-19-04-a-4175657824/

Kubuntu 19.04 Kernel 5.2.1
nVidia 430 Driver, Asus 970 Gaming/Aura, AMD FX 6300, 16Gig DDR3, 
Samsung 120Gig 850 EVO, AOC 29" Ultra Wide 2560x1080, nVidia 750Ti,
USB 3 Card, Drives 2TB, 1.5TB, 1TB

Reproducible on Kubuntu 19.04, Plasma 5.16.3. Could this be another side effect  of the switch libinput? The system notification KCM is completely grayed out, and the System Settings side bar shows two entries for Notifications.

FWIW: the Mouse KCM broke due to the library switch to make it Wayland compatible, suddenly missing configuration items.

This is about notification sounds, not input devices. Libinput shouldn't be affecting this at all.

Hi,

I'm also having the same issue as shown in the screen recording.

Using the same software in my other laptop (Slimbook Pro) everything works good. I don't know if the issue shows up when you change the volume levels, it becomes zero/muted and you cannot change it anymore. Not fully sure this is true, but I suspect so.

When you click on the mute volume button, you see the bar highlights a bit, but volume level stays zero. When you adjust the volume, bar darkens again indicating it got muted again.

I hope a solution is found shortly. 

Thank you!

I just found that after clicking on the mute button of the Notification Sounds bar, although the sound level is 0%, notification sound is back again! This is very strange, but it worked!!

just tried that and the mute button will click but do noting.

I had the same thing at first in the latest Kde Neon, then I noticed it's there also if you boot from the live media. Finally the same thing happened in a fresh install of Manjaro Kde. This can be solved by unmuting from a pkg called pavucontrol. I wonder if there is some terminal command to unmute without having to install anything. Anyway, pavucontrol can be removed once you unmute.

I hope it will be fixed because it's very annoying and may take a long time to troubleshoot for the end user.

just installed manjaro myself yesterday and yes it's the same there no notification sounds.

I have the same issue.

Operating System: Arch Linux 
KDE Plasma Version: 5.16.4
KDE Frameworks Version: 5.60.0
Qt Version: 5.13.0
Kernel Version: 5.2.5-arch1-1-ARCH

Audio:
phonon-qt5-gstreamer 4.9.1-1
Switching to phonon-qt5-vlc doesn't help.

I am able to change the System Sounds with pavucontrol only.

I found out that you are able to "bypass" this issue also using kmix (kde sound mixer)

What PulseAudio versions are you on? Works fine for me on the rather old 11.1 neon ships. Maybe the way plasma-pa manipulates the stream fails in newer versions.

Nevermind, neon dev unstable also affected apparently.

no new info on this yet?

(In reply to TheBeheader from comment #22)
> no new info on this yet?

how about some patience? The devs are aware and working on it, just not necessarily at the top of the list in their workload. With current GSOC drawing to an end and Akademy around the corner (to just name a few of the current events) everybody is very busy right now.

how about not being rude for no legitimate reason? i only asked a question.

o.k. long story short i just bumped my threads on both linuxquestions and the kubuntu forums and got my issue resolved. barfly prompted me to recheck pulse audio. on the playback tab system sounds were disabled. somehow i messed that tab in previous attempts to fix the issue. after enabling the sounds there i launched thunderbird to see if i'd get the notification sound for new mail and i did. this may not be a fix for all with the issue but worth at least look.

So, I just installed pavucontrol and set the System Sounds volume up from 0%. Now, I can set the Notificaion Sounds volume in Plasma Audio Volume Settings.
But I don't know whether it already worked in Plasma Audio Volume Settings as I did not test beforehand.

The problem is solved for me.

I'm pretty sure it didn't. I remember that, when I had this issue, only pavucontrol was finally able to "unstuck" the slider. So no, in my case (and probably also yours) it did not work beforehand.

It's solved for me too. Thanks

Problem persists in Ubuntu 19.10 with Plasma 5.17.0

i got lucky and my issue was a matter of going in to pulse and turning the sound on their to get my notification sounds, but shouldn't of been off by default in the first place. and yes it's off by default. i know cause i just tested kubuntu 19.10 and it exactly the same. now that said how about the devs weighing in here every once in awhile for those that we're as lucky as me and letting them know they haven't forgotten about this?

Can confirm this is still happening, on the latest stable build of Neon (20191226-1116). Although, all I had to do to fix it was install `pavucontrol-qt`, and all of my system sounds started working, like the noise when you increase or decrease the volume and notifications.

The issue is also present in Plasma 5.18.2 running version 5.5.6-arch1-1

The issue is also present in Plasma 5.18.2 running version 5.5.6-arch1-1

If it can help, I can manage to break notification sounds altogether (without even entering their settings) by doing

systemctl --user restart pulseaudio.socket

I had the same problem on Alpine Linux with Plasma 5.18.4.1, KDE Frameworks 5.69.0 and Qt 5.14.1. After installing Pavucontrol and unmuting it from there, I can now hear system sounds again and even control it via the plasma-pa KCM.

There's a patch: https://phabricator.kde.org/D28822

Git commit 5bdd1368957955c900d5a17bf6c890bb0920d356 by Nicolas Fella.
Committed on 15/04/2020 at 11:23.
Pushed by nicolasfella into branch 'Plasma/5.18'.

Create StreamRestore channel if none exists

Summary:
We need one channel to be able to control the volume. This restores D7485 which was broken by D20450 while fixing a different issue.
This patch tries to combine the two by only creating a new channel if none exists and not messing with existing ones.

Test Plan: Can control the notification volume in the KCM now. The slider position matches the one in pavucontrol

It's fixed in 5.18.5, which hasn't been released yet.

Cool was getting a bit tired of adding pulse components to address the issue.
