How Media controller or PA handle hda jack retasking of those 3 jacks
motherboard (channel mode or smart 5.1 switch) ?

For those mini ITX motherboard without front audio panel, there will
be no capture source if the HDA codec does not support stereo mix
after the driver retask those input jacks for 5.1 outputs

Does this mean that those 3 jacks , 5 jacks and 6 jacks desktop need
to add the rear panel jack to use snd_jack_report ?
