Hi,

I have to confirm the same fault on my all three computers with a driver snd_hda_intel in Plasma Environment. System sounds play too shortly + no sound (bubbles) for volume slider.

Solution:
- install a missing "phonon4qt5-gstreamer" and "phonon-gstreamer-common"
- logoff/login to Plasma. System sound notifications work well (System Setting → Notification → Plasma Desktop → choose some notification with a audio file → play)

Thank you Andy for the bug report!

Adding to the upgrade bugs tracker for visibility, even though comment 0 makes it clear that it happens also on clean installs.

@neoclust: Could you please take a look at this? Many users seem to be affected by this after new installations and upgrades, seems the default phonon4qt5-vlc is not working properly and people have to install phonon4-qt5-gstreamer to get KDE notification sounds working.

Related to bug #20954 ?

I don't think so - vlc works fine here, but regular KDE notifications only play a chopped-up sound, until phonon4qt5-gstreamer has been installed.

Although other applications may also be affected, see bug #20988.

Hi guys.  I did a clean install of Mageia 6 on one of my laptops today and ran headlong into this problem.  My machine also uses snd_hda_intel, but I don't believe this issue is specific to cards using that driver.

From my experience this afternoon, not only does the notification sound get cut off as a sort of lame *blurp!* but it also hikes the master volume up to 100%, which is to say that the two points in the errata ( "No sound from Plasma notifications" and "The volume of the sound changes suddenly to 100% during a Plasma session" ) are two side-effects of the same bug.

Hopefully someone else has pointed this out already, but digging into the problem more or less confirmed my suspicion by leading me to this KDE bug report from 2013:

https://bugs.kde.org/show_bug.cgi?id=345651 (RESOLVED FIXED... or is it?)

There the bug is batted around by the likes of Colin Guthrie, Wolfgan Bauer, and a couple of other names I recognized (as I'm sure anyone who's been around a while will).  The thread left me with the impression that Hrvoje Senjan may have been the originator of the "flat-volumes = no" workaround.  If you haven't read through it before, you may find the discussion there informative as to the bug's  origin and underlying causes.  And sadly, no it is most definitely neither resolved nor fixed.

As some of the reporters in that thread point out, unsuspecting users listening to music through headphones in a Plasma 5 environment (as well as more recent KDE4 configurations) risk sudden hearing damage when a system notification spontaneously cranks the volume to 100%.  IMO this is a fairly serious concern and Mageia should have shipped with gstreamer as the default Phonon backend rather than VLC.

So far Mageia 6 seems great, though for a number of reasons Plasma 5 is leaving me feeling rather underwhelmed. (What have they done to ALT-TAB switching?  Ungh!  I want my cover switcher back...)

Oh silly me. I put in the wrong link to that KDE bug report. Here's the one I meant:

https://bugs.kde.org/show_bug.cgi?id=324975

Fix for https://bugs.kde.org/show_bug.cgi?id=324975 is now in mga6 updates_testing

Shouldn't this be assigned to QA team then so it can actually go through QA validation so it will be pushed as an update eventually, or is there anything missing (apart from the package listing for the advisory) ?

src.rpms:  task-plasma5-5.8.7-2.1.mga6
           pulseaudio-10.0-1.1.mga6


Advisory:
This update disable flat_volume by default, fix sound resetted by default at login. This update install by default phonon gstreamer engine to allow smooth update from mageia 5

Assignee: kde => qa-bugs

Update tested into VM MGA6 64bit fresh installation:
KDE notification sounds and flat volume is working well now.
