I have figured out part of the value I need to assign: a black 1/8''
jack for speakers, rear external, will be 0x01111xxx.
I am having hard time figuring out the last 3 numbers:
- only the last one of misc bits is defined in the spec (jack sensing
override), yet the bios test it to values > 0001 for some of my jacks
- the default association and sequence seem to have more choices, should
I steal these from other pin configs to make it work with 8-channel sound?
