PulseAudio switch-on-connect and device-manager modules

[Nate Graham]

Howdy folks,

It seems that we have KCMs that conflict with one another: 
- The Phonon Audio/Video KCM uses the module-device-manager PulseAudio Module.
- plasma-pa's KCM has an "Automatically switch all running streams when a new output becomes available" checkbox that loads the switch-on-connect PulseAudio module.

...But both modules can't be loaded at once. So plasma-pa's "Automatically switch all running streams when a new output becomes available" checkbox does not work in many circumstances.

This is all relevant to our users who would like to have audio streams automatically switched over when a new device becomes available (e.g. a bluetooth or USB headset) and report that checking the "Automatically switch all running streams when a new output becomes available" checkbox doesn't enable that behavior for them.

What's our path forward here?

Nate
