I've just hooked up an Oppo 980H DVD player to a Pio Elite VSX-90TXV
receiver, but for some reason I do not get audio through optical
connection: HDMI cable comes out of the 980 and connects to one
of the HDMI inputs on the 90TXV; Optical digital audio comes
out of the 980 and connects to one of the inputs on the receiver.
However the only audio I get is through the TV speakers, and
only if HDMI audio out is turned on on the 980. Page 16 of the
receiver says something like: "to hear audio from your HDMI device
through this receiver, make analog and/or digital connections as
necessary. Without this connection, HDMI audio will still be output
*from your TV*, but no sound will be heard from this receiver".

Nevertheless, even with the connections made as indicated in
the manual, I don't get audio from the A/V receiver's speakers.
Does anyone know any issue with the combination 980H +
90TXV? Thanks.
