Computer won't post when using display port to hdmi adapter for audio through reciever with Vega 56

Since Vega 56 only has one HDMI port and three display ports, I require a displayport to hdmi adapter that I run to my receiver so that I can get uncompressed 5.1 audio. I use the HDMI out to go to my tv because my tv doesn't have any display ports. Unfortunately my computer wont even post when i'm using both the adapter and the hdmi out. All the fans and lights are powering on, but nothing will post and it lets me shut it off by pressing the power button as no attempt was made to get past the bios screen into windows and my tv just says no signal. If I use the adapter only it works, or if I just use the hdmi out it works, but not both at the same time.

 

I can plug in the adapter after I boot and it works fine.. It just wont boot if they are both plugged in. I have tried two different adapters and two different Vega 56 cards and all of them exhibit this behavior.

 

I don't want to have to manually plug in my audio every time I want to use my computer. Is this a known problem, or am I seemingly the only person in the world trying to run this setup? I've found nothing else relating to this on a google search.
