Question/Feature Request: Sync master volume between PulseAudio server & JACK server while using bridge

[ewancg]

Using the ALSA backend with JACK & the PulseAudio bridge, is there a way to mix JACK's master volume to match that of PulseAudio's? Currently, this is the only thing stopping the JACK/Pulse experience from being completely seamless for me. I'd like to be able to use my DE's PulseAudio applet to control the volume of the entire audio stack, because that's how it worked for me when I was only using Pulse.
