|- off at a slight tangent in terms of possible resolution to missing sub-woofA (woofer...) as currently being discussed... OtH's explanation is fine; and does point to possible issues that are affecting why you can't get it to work at this stage...|
I'd be inclined to go for an external amp system (preferably hard wired - real cables), and pass all audio o/p sources that merit it through that. Thus the Bluray becomes a source of audio/video and no more than that. Use good quality cables and connectors too.
More than likely too the quality of an eternal amp o/p will be superior to whatever the Bluray puts out?
Like OtH I tend to avoid wifi systems - unless absolutely essential/no- really viable alternative. Interference is one issue; hacking another if pc related; not forgetting the possible nasty/side effects of having wifi frequencies all around you all the time; and which may/may not be good for you...? (And I'm not going to go down that latter path here...; it's well discussed elsewhere "out there" - Scully...)
