Do you mean one combo jack for hp or ext mic ?
Do you mean hp auto mute speaker work ?
There are two [Pin complex] 0x1b and 0x1d which can be retasked as Input or
Node 0x1b [Pin Complex] wcaps 0x400581: Stereo
Pincap 0x00011334: IN OUT EAPD Detect
Node 0x1d [Pin Complex] wcaps 0x400581: Stereo
Pincap 0x00010034: IN OUT EAPD Detect
Does the user manual mention about the speaker mute button or mic mute
button and thow the combo jack work (e.g. auto detect hp or mic) ?
