Does the HDMI Expansion support audio output via HDMI? I am trying to use the HDMI port to play video and sound on my TV. I am missing a driver or is further driver development needed? I am using:
Edition Windows 10 Home
Version 21H1
Installed on 8/3/2021

Experience Windows Feature Experience Pack 120.2212.3530.0
The HDMI Expansion Card does support digital audio over HDMI. Could you check if the TV appears as an output device in the Sound settings in Windows 10?
I am so sorry, I did try another TV before posting, the drivers work on another TV. The issue is with Vizio TV.
Could you share the model number of the TV and ideally the cable too when you have a chance?
Is there a soundbar you are using with it? If so, make sure it is in the eARC port for the audio to go to the bar.
Vizio No audio for M50-1D
Make sure the sound mixer output is set to the TV too so it pipes it to the HDMI port instead of headphones or speakers.

It could be the APU output for the 4K display. Which CPU did you get?
Try the Vizio support first before looking at drivers or extra things needed to work with that specific one.
