convert audio receiver to wireless for home theater

[omnichronos]

I have 5 wired ceiling speakers that are connected to my receiver. My 4k TV is the other side of the room. How do I get a wireless connection between my receiver and TV? I can also connect a Roku to my receiver if streaming the video is better than streaming only the audio. I don't want lag between audio and video.

There are wireless audio bridges (I'd look for RF based ones), but they are stereo only. For surround sound, you'll have to pull some wires - either speaker, or very long optical/coax SPDIF. I doubt there are wireless HDMI bridges supporting HDMI ARC.
