Please read the following: http://pulseaudio.org/wiki/DefaultDevice This is the difference between default in the sense of "use it always" and default in the sense of "use if it you don't have any other information". > So, I need a solution that does either or both of the following: > > * Makes gnome-volume-control actually assign an application to the > microphone that is selected in the Input tab (*gasp* how logical). With input I agree, but the "logic" is not always correct considering the memory of PA to restore to where you last used that application (for output streams at least) as covered in the above link. > Any ideas on how to get to the bottom of this? Well it should just be a matter of either: a) Remove the stream restore database for that user. (rm -f ~/.pulse/*stream-volumes*) and set the USB as default prior to any apps recording sound. b) Move the stream once in pavucontrol to the correct input device and it will be remembered thereafter.
