First HTPC for gaming. Will a KVM transmit Dolby Digital Live/DTS Encoding from a dedicated soundcard to a receiver?

I'm attempting to create a simple gaming HTPC with a dedicated soundcard (like Sound BlasterX AE-5) for live encoding for DD and DTS while also using a KVM for 4k60fps to a 5.1 receiver with 4K passthrough via HDMI ARC. I have no experience with any KVM before and have been browsing through products on AVaccess's website. My Google Fu has failed me and I haven't been able to find any definitive answer for my setup.

I want to be able to use my gaming PC on my 5.1 home theater a few rooms away without having to move the entire desktop at 4K60fps with Dolby or DTS.

Thanks so much for any help
