I suspect the input jacks are incosistently labeled. Can you try changing the file /usr/share/pulseaudio/alsa-mixer/paths/analog-input-dock-mic.conf


code = Microphone
name = Dock


code = Microphone
name =at Sep

(notice the space between "at" and "Sep")

Then reboot and see if that helps? Thanks!

Yes, that made the dock mic jack sensing work. What about the output? There's no "docking station headphones" at all in the sound settings? Also, where should I go to fix the jack labels, as I assume the "at Sep" isn't the commonly used label?

David Henningsson (diwic) wrote :

A big part of this problem is that the HDA kernel driver is fragmented, so the code used for IDT codecs is different from the one from Realtek codecs. And so they use different naming conventions, and I chose the Realtek convention here.
I intend to fix that up for the P cycle, so that then naming convention is similar.

For the output, that's actually a line-out (rather than headphone) jack, or at least is listed so by BIOS, and IIRC jack sensing for line outs is not implemented in the IDT kernel driver.

I'm running Lubuntu 12.04 and this does not work for auto sensing the Dock line out.

Can you identify a fix similar to the "at Sep" for the Dock mic?
