Streaming app doesn't have surround sound? pt#2 - XFinity

There was a previous thread on this marked as "solved" but "We can't figure out how to do this so we deleted the capability" is not a "Solved" answer. I just switched from DirectTV specifically to get HD and surround sound which DirectTV offers on 100% of it's channels. It is unacceptable. My Roku Express decodes 5.1surround when you use google movies or

Showtime apps but when you try to watch the same Showtime show through xfinity express it only presents in stereo.

This is not acceptable. Is it possible to get a free receiver box until this is "Solved"?
