Normally the fallback button should work in standard pavucontrol, are 
you sure you
do not have a modified version? Did you try pavucontrol from git?

I have no idea what is happening there, but this is definitively not a 
pulseaudio or pavucontrol
issue. Something else must cause cycling through your devices. The way 
pulseaudio works,
it remembers the sink you choose for an application, so it should keep 
on using the same sink.
If PA would go cycling through the devices, I guess we would receive 
really lots of complaints.

In pavucontrol there is a volume limit of 150%. Again it seems you are 
using a modified
version. pulseaudio itself however does not have a volume limit. Using 
pactl, you can adjust
the volume to more than 150%.
