So I think there is an additional problem debugging this.  Somewhere in the
backend database or in the frontend it remembers your Digital Audio
Capabilities. The system I was testing this on was built from scratch as a
FE/BE combo. Brand new database. The first version used was fixes/32 from
the end of July.  So it showed the "no 5.1" issue.  When I took the build
back from 32.0-59 to 32.0-08 it worked and I could add in the Digital Audio
capabilities. But because it's now stored somewhere, every build I do still
has the same results.  Dolby Digital works.  I even had this problem on my
FireTV.  Once the backend is connected with a frontend, it remembers its
settings, even without the unique id set.
