Created attachment 129134 [details] Messy audio device display My new laptop--a Lenovo ThinkPad X1 Yoga--has a very messy audio device selection in the plasma-pa KCM and applet. It displays three devices for HDMI/DisplayPort audio (two for the two Thunderbolt+DisplayPort ports, and one for the HDMI port). Each of these devices has a single port, which is listed as "unplugged" in pavucontrol, accurately reflecting their status. We should consider filtering out devices with a single port that is listed as "unplugged" because interacting with them does nothing and therefore they are simply visual clutter.
A kernel update fixed this issue. I guess lower in the stack is the right place to go when you've got this problem.
Nah, that's not correct. Re-opening since it's still sometimes relevant.

Git commit 6611ff9e89ecedbedb38c630ece042d57832f72c by Nate Graham. Committed on 19/06/2020 at 05:07. Pushed by ngraham into branch 'master'. Filter out currently unused devices Right now devices that have only a single unplugged port are visible in the applet and the KCM. For all intents and purposes, these devices are useless as they are inactive and unused. Therefore, let's filter them out so they're not distracting and confusing to the user. An option to see them all again is provided in the KCM on the off chance that a person needs to configure the volume or balance of an unused device *before* it's used. This patch is principally aimed at people using hardware where PulseAudio represents multiple input and output sources as separate devices rather than separate ports of the same device. I asked the PA people about this and they said that for certain hardware, it's intentional, and the correct approach is to filter out the unused devices over here [1]. So, that's what this patch does. Thanks to @nicolasfella for his help with getting the initial prototype working!
