<p>You will get auto mute lineout+speaker if the pin fixup is dock line out instead of dock headphone but pulseaudio don't like headphone and line out share pcm playback volume control and no headphone playback switch</p>

<p>For notebook with dual headphone jacks which support multi channel and headphone Jack won't mute the other headphone Jack </p>
<p>As you expect headphone can mute dock headphone and speaker</p>
