Do you mean Pulse will change the output device rate depending on what is
playing? That sounds like it would break the jack/PA dbus interface. (even
more than it is now) Maybe not. What will it do with things like gphone or
skype where the incoming audio may be at 44.1k but the mic runs at 48k
(only)? This is not uncommon BTW. I have already had to change the default
on my netbook in pulse so that the built in mic would work.
