Sometimes I see "Device name not found" in plasma-pa applet of neon unstable too. In my case I think it is related to remote pulseaudio server that I use to stream audio, via local network, from my laptop to speakers connected to my desktop computer. I just noticed that the bug seems to trigger if I disable an output. In my case, I have a USB DAC and the GPU's HDMI output; if I disable the latter, the unknown device shows up. It seems then like the device is not removed from the list of the applet and therefore appears like an unknown device. lol weird Created attachment 132600 [details] screenshot taken on neon unstable (In reply to Patrick Silva from comment #1) > Sometimes I see "Device name not found" in plasma-pa applet of neon unstable > too. > In my case I think it is related to remote pulseaudio server that I use to > stream audio, via local network, from my laptop to speakers connected to my > desktop computer. I can reproduce with these steps: 1. start Plasma session on server machine 2. start Plasma session on client machine 3. suspend server machine to RAM "Device name not found" appears in plasma-pa applet and I need to restart Plasma session on client machine to get the correct remote pulseaudio output in plasma-pa applet again. Can you attack `pacmd info` from before and after disabling the output? Created attachment 133351 [details]

Here are the outputs of the command before and after disabling the output. Let me know if you need anything else.

Remove count property from PulseObjectFilterModel PlasmaCore.SortFilterModel already has a count property that does what we need. For reasons that I don't fully understand this extra count property confused the view in such a way that extra "empty" sink items were visible in certain circumstances.
