won't auto-select input when headset is plugged and selected in pop-up window

To fix this issue， there are 3 fixes for 3 different packages:

libgvc (no response from maintainer): https://gitlab.gnome.org/GNOME/libgnome-volume-control/-/merge_requests/10

pulseaudio (rejected by maintainer): https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/295

gnome-control-center (upstream provided and merged a fix): https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/1033

So only got the fix for gnome-control-center so far.

Thanks, there is no point uploading only the gnome-control-center part for now right? We will keep an eye on the other merge requests, the pulseaudio discussion seems active though (you mentioned it was rejected but it seems not yet, or at least solution are being discussed?)

It is a bit helpful on this bug if we could merge the fix of gnome-control-center first, without the fix of gcc, suppose users manually select the preferred input device, the system will not store user's selection, but after applying the fix of gcc, the system could store the user's selection.

So the fix of gcc could partially fix this bug (after freshly installing the OS, need users to manually select the input device once). After those all 3 fixes are merged, the auto selection could work out-of-box, no need the users manually to select anymore.

@Hui, thanks, we also got confirmation on bug #1876267 that the g-c-c fix by itself helps. I've uploaded to the G-serie now and commit to the focal vcs for the new SRU upload

This bug was fixed in the package gnome-control-center - 1:3.36.3-1ubuntu2

If we still need to land in focal, shall we affect focal series for g-c-c?

@Yuan, yes, it's fine to do but the SRU team usually create those when accepting the upload
