Hi,

in my setup I disabled all pins referring to "Unknown" and I disabled pins I 
don't need by setting as=0 without having any issues. I put Headphones and 
Speaker in same association (anything between 0 and 15, not 0, not 15), then I 
gave Headphones seq=15 and Speaker seq=14. As mentioned in manpage seq=15 for 
headphones will duplicate first pin in association, that would be Speaker. If I 
remember correctly online reconfiguring of device using dev.hdaa.*.reconfig 
sysctl-variable produced in some cases different devices than rebooting system 
with same changes of default configuration in device.hints.
