Audio through Lenovo OneLink Pro Dock DP port

So I have a Lenovo Yoga S1 and a OneLink Pro Dock. The Dock is connected to a TV trhough a DisplayPort -> HDMI cable. On Windows 10 after some Intel Video Driver update I was able to choose my TV as an audio source, so I could get audio+video through DisplayPort. Now I would like to do so in Arch as well. Problem is, it is not listed in my sinks.

PulseAudio sinks, sink 0 is a mini-hdmi port located directly on laptop, 2 is the internal soundcard, 3 is the jack on the docking station. No DisplayPort output listed:

pactl list short sinks
0	alsa_output.pci-0000_00_03.0.hdmi-stereo	module-alsa-card.c	s16le 2ch 44100Hz	SUSPENDED
2	alsa_output.pci-0000_00_1b.0.analog-stereo	module-alsa-card.c	s16le 2ch 44100Hz	SUSPENDED
3	alsa_output.usb-C-Media_Electronics_Inc._ThinkPad_OneLink_Pro_Dock_Audio-00.analog-stereo	module-alsa-card.c	s16le 2ch 44100Hz	RUNNING

xrandr, eDP1 being notebook screen, DP1-1 monitor connected through docking station via DVI-I, DP1-2 being TV connected through docking station via DisplayPort:

eDP1 connected (normal left inverted right x axis y axis)
   1920x1080     60.04 +
DP1-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
   1920x1080     60.00*+
DP1-2 connected (normal left inverted right x axis y axis)
   1920x1080     50.00 +  60.00    59.94    24.00    23.98

How can I get Arch/PulseAudio/Alsa to recognize my DisplayPort output as a valid sink?
