Surround sound beta not working w/Comcast Cisco RNG-200N cable box

I can't get surround sound from my Cisco RNG-200N to Xbox One to Sony A/V receiver (Sony STR-DN1040) to work even though I have 'Surround sound beta' turned on. When I plug the Cisco RNG-200N directly to the A/V receiver it works just fine, it indicates Dolby Digital surround and I can hear sound coming from my rear speakers. I've and to disconnect the HDMI passthrough for the time being but would like to fins a solution to this issue so I can enable this again. Thanks.
