firefox/flash and pulseaudio

[Danny Yee]

Can someone confirm that firefox/flash is using pulseaudio on their
system?

That is, if you run pavucontrol while listening to a youtube video
(or something similar) in firefox, can you see the audio stream?

Looking at this diagram

it certainly doesn't seem right for firefox/flash to be bypassing
pulseaudio.
