2. DeviantArt Thread
I also found another thread mentioning a prior version of a Huion device, Huion GT-185 HD. This is a tablet monitor which I assume is the same type of item as your Huion Gt-220. The thread was on DeviantArt page for the GT-185 HD device.
In the thread a Huion support staff made the point that these tablet monitors do not include audio.

Kindly note that there is no audio device in the monitor, so it can
not give off any audio.
They then went on to suggest that the ordering of the displays mattered because of this fact.
huion Oct 23, 2017 Hello,
Yes, it supports extended mode. Kindly inform you that if you want to
use the monitor in extend mode and then use the pen on the HUION
monitor, you need to go to control panel to identify Huion monitor is
recognized by which monitor in your system. For instance, if GT-185HD
is monitor 2 in your system, please select Monitor 2 in the driver. If
you have selected Monitor 2, but you still couldn't use the pen on it,
please try to select "all desktop area".
