I'm having the same issue. Running Ubuntu 16.04.2 LTS with kernel 4.8.0-45-generic. Audio jack on laptop works fine, but the audio jack on dock doesn't work at all.

Without the dock, everything works, headphone/mic jack on the P50 itself is hotplug (switches from speaker to headphones right away). Screenshots (with and without docking station) attached.
