Vizio AIOPC sound issue...

So, I am at a loss. I purchased a Vizio ca24-a4 aiopc with the knowledge that the sound wasn't working properly thinking I could fix it. While for the most part I have (bluetooth speaker, much) there is something odd going on here I don't quite understand.

The onboard sound doesn't work initially. But if I go to playback devices>configure>test the sound begins to work perfectly... and then tapers off into not working again. No amount of driver updating or whatnot will help fix this issue. I've checked the hardware itself and it all seems to be fine. Bluetooth audio works perfectly as well. Then comes the really weird part. This PC has the ability to be used as a display for other HDMI devices, and when I use it as a display only the sound works perfectly. Even with the PC powered off. Hmm....

I'm not a novice, but far from an expert and I just don't know what is going on here.
