Which I suppose is reasonable for a TV with only stereo speakers, the
fact that it's been told to forward the digital audio signal on out
through it's optical connection.

Not sure what "digital audio output" means in this context, but as I
mentioned before, I am able to get 5.1 DD/DTS through this configuration.

TBH, I'm not sure what it reports in terms of the "connection" in the
audio setup.  I really ought to look but that box is being retired, or
at least demoted.

Well, it does seem odd to be able to get 5.1, admittedly encoded in
DD/DTS but having Myth telling me that the audio is only 2.0.

Not really sure how to rectify that though given the information
available to Myth.

Cheers,
