How does an os12 port get initialized ?!
========================================

kernel doesnt do anything

disables watch dog timer

initilises OE (output enable array)

osOpenPorts
	resets all codecs
	hdaport::init
		sets control reg
		sets latch direction reg
	sets time slots
	sets oe
	sets codec reg 0x32

Port is now "Open"!

playrec.cpp now sets some things
hardware gains are set
hybrid balances are set

Channel is now "open"
