What causes audio delay coming from HTPC?

[FAHEYGF87]

Here's my setup:

 

HTPC(B550 R5-3400G)

Xbox one

Nintendo switch

Dish set top box

Denon receiver(I forget the model)

All connected via HDMI

 

Everything goes through the receiver and to the TV/Polk audio speakers.

 

Here's my problem:

 

ONLY THE HTPC will get out of sync with the audio/video. It doesn't matter how much I play with the audio delay function on the receiver, it seems to develop a delay after a couple minutes of playback.

 

Since the xbox/switch/dish all work fine, i've deduced that it isn't an issue with the receiver. 

 

So what issues within Windows 10 would cause a delay?

A fixed delay? Does it get worse over time? Will it reset randomly at some point and start to get larger and larger again? What content cause the delay and how is the HTPC plugged into the receiver?

If you use MPC-HC, the internal audio filter has an AV sync fix.

It does seem to get worse over time. I wake the htpc up from sleep with the keyboard. Open Netflix or Disney +, it plays fine for a few minutes before my wife elbows me and says "it's off again" (she is more sensitive to it then I am), then another minute or two go by, and I notice it too. Last thing we tried to watch was Agents of shield on Netflix.

What is MPC-HC? If it's not something that happens by default, I'm probably not using it.

Use ARC over HDMI instead of using your receiver as an HDMI switch.

Isn't that how a receiver is supposed to work though?

These issues crop up all over the place with receivers and ARC would just solve it, that's why I suggested it.

So HTPC into HDMI 2 on my TV, then ARC down to the receiver? I'll give it a try.

I don’t know how many HDMI jacks you have but you could pop everything into the TV and just use ARC as a single input into the receiver as well. 
 

But yeah, what you suggest will work. It’ll also give you access to all of those extra HDMI inputs on the TV if you run out of them on the receiver.

That's a long dead media player I use. Here's its afterlife, however, might worth a try: https://github.com/clsid2/mpc-hc/releases/
