Naming: Right now, this is browser-wide audio mirroring.  So, maybe name it
something like AUDIO_MIRROR_ALL?

I think this is an odd name and if you plan to use this code in the future for
non-browser mirroring then it'd be worth keeping the name generic.
AUDIO_MIRRORING or AUDIO_VIRTUAL sounds better to me, but it's up to you.
