SUMMARY After the recent update to 5.19.4 most of my audio devices have disappeared such as analogue output, USB webcam, and others. A USB headset still remains. STEPS TO REPRODUCE 1. Connect various sound devices - they are all visible when clicking the volume icon in the system tray. 2. Update to 5.19.4 OBSERVED RESULT Many of the devices will now have disappeared with no way to get them back. EXPECTED RESULT The devices should have remained. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE neon 9.19 KDE Plasma Version: 5.19.4 KDE Frameworks Version: 5.73.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION Various other bugs were introduced with this update but this is the most serious so I will report those separately at a later date if they aren't fixed soon.
Please attach a screenshot and the output of running "pactl list sinks"
Created attachment 131258 [details] Output of "pactl list sinks" as requested.
I assume you are talking about the Neon 18.04->20.04 update? From the output I can tell that PulseAudio only reports one output device (the headset) so Plasma is behaving as expected here. The devices disappearing is likely caused by the new PulseAudio version from Ubuntu 20.04
Another way to check would be opening pavucontrol or pavucontrol-qt If the devices appear there but not in Plasma it's a bug in Plasma, if they also don't appear there the bug is in PulseAudio or lower
Like I said in this forum post (https://forum.kde.org/viewtopic.php?f=309&t=167621&p=436838&hilit=pipewire#p436857) the issue seems to originate from the kde neon provided pipewire package. Reverting to Ubuntu version seem to fix the issue, not just for myself but other people too (https://forum.kde.org/viewtopic.php?f=309&t=167621&hilit=pipewire&sid=db82cb5d66300d2a9743449450faafc8&start=15#p436890)
Today I'm on a computer that has not been updated and both sound and Shutter work perfectly. To confirm, it was indeed the update to "KDE neon on 20.04" that caused all the issues. I won't be updating this computer but I would like to roll back my other computer if possible? I will be forced to re-install otherwise.
"pavucontrol" has allowed me to find and select the correct audio device - thanks!
I will let you decide if this bug should be marked as resolved or as unrelated to KDE.
(In reply to Paul Feakins from comment #7) > "pavucontrol" has allowed me to find and select the correct audio device - > thanks! Did you managed to select the audio device once you downgraded the package pipewire from 0.3.8-1+20.04+focal+build1 to 0.2.7-1? Because if that's the case, while not technically a kde problem, it would be a kde neon packaging bug. Version 0.3.8-1+20.04+focal+build1 of pipewire is provided by the kde neon package archive.
Thanks for the reply Martin, this was indeed after I had downgraded pipewire and rebooted but that alone had not fixed the issue.

What you're seeing in that bug is actually subtly different from what I'm seeing. You mention the volume icon is greyed-out, but for me the icon is there, I can click it, and some outputs are shown - digital ones - but the analogue one I would usually use was not there. As above, pavucontrol allowed me to select it and get it back.

I think it may be because we have different hardware, for my case I suppose that all my audio hardware is controlled by Intel HDA Sound in the intel chipset, that's why I have only dummy output. My guess is that hda_intel outputs are the one affected. Do yo have several audio outputs/hardware managed by different chips?
