Yes, DP audio without adapter works both on the laptop DP port and the docking
station DP port.

I added new logs for the following cases (same display was used for all tests):

Internal DP connector to DP display input  -  works
Internal DP connector via adapter to HDMI display input  -  works
Dock DP connector to DP display input  -  works
Dock DP connector via adapter to HDMI display input  -  does not work
