Bug 1173720

I also tried to launch the live version of Leap 15.2 (KDE) with the same results. So it is not an error in the transition from the previous release.

With the speaker-test command I can listen to the sound through headphones and adjust the volume with the Yast controls, but in Yast the button to test the sound does not give any output. It looks like a configuration problem, but I don't know where to take action.

The problem concerns pulseaudio and not the drivers, as I initially thought. I modified the configuration in /etc/pulse/default.pa by uncommenting a couple of lines (as indicated by the arrows) and now pulse also recognizes the headphones and the sound works, but it seems very slow to initialize itself and in the graphic controls (KDE). Anyone have any idea how I could better modify the configuration to restore smooth and correct operation?

Hrm, not sure what went wrong in your case.  I'd rather try to remove the stale config (align /etc/pulse/* from the distro default and remove ~/.pulse* and ~/.config/pulse* directories), and re-run "setup-pulseaudio --enable" once.

I did the test you suggested, but nothing has changed. But I have done other research and tests and I have found that it is the detection of the audio jacks. So I modified the following file: /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf (see below the content with the two commented lines indicated by arrows) and the audio headphones have turn back to appear in the drop-down menu and now they work perfectly. However, their connection is not detected and therefore they are always active even if disconnected. I guess the same goes for all other analog outputs, however I think there should be a way to automatically correct this jack setting, without changing all the files by hand.

Then it might be rather because of some kernel driver issue, just surfaced on the recent PA.

Please give alsa-info.sh output.  Run it with --no-upload option and attach (no paste) to Bugzilla.

Ok, I ran the command alsa-info.sh and attached the output.

Friends do not insist more than this and pulseaudio they will not fix it. They don't care about those little ones. It worked perfect and in one go in version 15.0 and 15.1. You have to wait for 15.2 to see if it is solved by a miracle.

Hmm, i guess that depends on the 'little ones' being Leap as opposed to Tumbleweed ?
Because Tumbleweed is what i am one - so as a rolling release, i can prepared to put up with immediate
changed that can cause disruptions, bugs etc etc...But....I expect all leap users to be priority No 1
for any/all bugs - as your the 'stable' release

My Internal Motherboard Intel GPU HDMI no longer exists as far as kde plasma's audio settings are concerned
Hope this gets fixed for both out sakes :)

Erm this has been forgotten as NEEDINFO flag wasn't cleared.

Leap 15.2 was already discontinued.  Please create a new entry if the problem is still seen on Leap 15.3 (at best test with Leap 15.4).
If it's seen on TW, create another bug, too.

Thanks.
