I admit that the best thing would be to make the driver support all three mics, but at this point, the alsa driver can only support two, one called "mic" and one called "front mic". I believe the best choice is to select the internal mic as "front mic" and the mic jack on the laptop as "mic", thus leaving the docking station mic jack non-functional.
The behavior without this patch is to select the mic jack on the laptop as "mic" and the mic on the docking station as "front mic", thus leaving the internal mic non-functional in all cases, and that regardless of you have a docking station or not.
This is no 100% fix or regression fix, so not suitable for stable kernel tree, I suppose.
I'll post a bit more intrusive patch for fixing this.
thanks,

For laptops you would want to take preference of the docking jack over the interal mic if you are in a docking station.
So if you do plug into a docking station and you have a microphone in the docking station, a user would want to use that over the internal microphone. You wouldn't want the laptop internal mic preferred over the docking station microphone.

The BIOS of Dell Precision M6500 lists both 0x0e and 0x11 as front mics, and the driver only supports one front mic. This commit adds a quirk for preferring node 0x11 (internal mic) to node 0x0e (possibly docking station mic).
