I had the 5.1 working on mythtfrontned v32.0-6 on my FireTV, but today I
rebuild the android mythfrontend to v32.0-59 and now I have the grayed out
Digital Audio Capability the same as on my x86_64 versions of
mythfrontend.  So something changed since March because my hardware and
setup has not changed.
