Does this mean that pulseaudio don't support notebook with dual headphone
jacks since you need to use  jack states of both headphone jacks to
determine the speaker is muted or not even you assign different name to the
headphone jacks

For notebook with dock station ,  headphone jack and dock headphone jack
usually share volume
