I decided to just buy this.
I'm not sure how I'll go about changing from PC to Switch on my monitors but at least this way, I won't have to use the terrible speakers on my monitor.
edit - Actually I canceled it after I realized I could just use the headphone jack while the Switch is docked.
There's no good way to do it honestly.
Theoretically the best way would be to use RCA cables (Wii Composite) and convert to 3.5mm and amp it, but WiiU's don't have that on by default.
You could also use the headphone jack on a monitor/Gamepad and amp it as needed, but that can be inconsistent by monitor/TV
The way to garuntee getting audio at every setup is to get an HDMI audio extractor and run it through a headphone amp if you need some extra volume
