Sounds like you just need a HDMI 2.0a (or better) 4K/HDR compatible Splitter
right after the XBox.
Other "black boxes" might do something similar or split-off an acceptable audio tap. Kinda surprised the XBox-One doesn't have that already.
If what you need costs as much as Joe says, then upgrading AVR might be a wise choice. You will be all caught-up for these consoles and hopefully the next set.
You need a really-nice (high bandwidth) HDMI cable going to the projector, or all this is for nothing.
