Yeah AG620x is the most common and doesn't mess with sync signal.
Only problem is it has the limited-range bug, but that's manageable.

I've tested the audio with all my vga adapters.
Seems like the "tail" adapters have the cleanest audio and quietest noise floor, especially the UGREEN which has superb build quality.
Probably because the 'tail' adapters are bigger and have more space for better audio dac chips.
The flat (striped white/black/gold) adapters have faint hiss and noise when audio plays.
All support 96kHz.
I recommend this one;

The HDMI port on the DE10-Nano provides enough power so no need to externally power these adapters.
