In the new (2.27.x) gnome-media I noticed that switching from "Output analog stereo" to "Output analog stereo + Input analog stereo" leaves the input device (Input tab) unused: the device is selected (row has active background) but the radio button is not active (see screenshot)
Can you please make sure you use the full versions in bug reports?
Can you reproduce this with gnome-media-2.27.91? Which version of pulseaudio was used?
If you can still reproduce this, please attach the full output of "gnome-volume-control --debug" when reproducing the problem.

IIRC there was only one 2.27 gnome-media release but the full version is gnome-media-2.27.91-1.fc11.i586 and pulse is 0.9.15-17.fc11.i586
Looking at the code, I can only think that PulseAudio is at fault here.
Could you please attach the output of "pulseaudio -vvv" when reproducing the problem?
It should show whether notifications about the new device have been pushed to the clients.

Yes, this is probably a bug in PA indeed.
Fixed in PA upstream now. Will be fixed in rawhide too, as soon as i do another upload.
