This 1600EUR dell monitor is just a POS :) But sadly it will not be the 
only POS out there, as there's a lot of cheap S out there as well (coen 
brothers rockà :)).So our only option is to have users state: "Yes, i am 
certain that i want audio pushed out over this link"

Hence the option for persistent audio capabilities, or an randr 
"property" for those who change their minds afterwards. It's the best we 
can do if we have no extra info from the monitor, and we do get extra 
info, we will need a way to override this as well :( Nothing is ever 
easy or straighforward in this game :)
