My sound system has multiple HDMI ports. I connected an old laptop to one of those HDMI ports and use it's internet connection to get the streamed signal. I originally used wireless from the laptop to the TV, but latency issues made it act up. The hard wired HDMI took care of that.
I leave the laptop on in the corner signed onto OAN.. When I see something interesting on OAN, I just switch from HDMI 1 (satellite) to HDMI 3. I get full surround sound and a perfect picture on my 82" Samsung flat screen.
The OAN streaming service is only $5/mo... worth every penny to watch Dan Ball's Real America program.
