Public bug reported:
Lenovo Thinkpad P50 with docking station
Issues: Headphone jack on station not detected; no sound (works without docking
station)
Issues: Sound via HDMI on station not detected; no sound (works without docking
station)
Since all outputs are routed via the Thunderbolt chip, my guess is that
it's related to the pin setup (lenovo-dock) in Alsa. 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.
Thanks and LG,
Wolfgang
