Same situation here.

Sounds like a good use-case

Sounds like you need to be able to instruct Myth to decode AC3 for 2ch
(and sent it via PCM) and pass it through for > 2ch.  Sounds
familiar.  :-)

Sure.  But should everyone have to have their AC3 decoded because it
fits one use case?  Or should everyone have to have their AC3 passed
through because it's another's use-case?  Sounds like some flexibility
is in need here, which is *exactly* what I was asking for/proposing.

TBH, I don't think that's fair.  It's inconsistent only because it
satisfies one use-case.  It even rang inconsistent to you when you
decided to fix it.  IMHO, this is just more evidence that flexibility is
needed.
