It can only output sound from a HDCP source, to another HDCP compliant source. This was to prevent coping of the 5.1 audio. Optical doesn't support HDCP. This is why it was disabled on the W4500, even though it's technically capable of it, similar to region coding. HDCP doesn't apply to the internal freeview tuner, hence why it's able to output 5.1 from the optical. |
I just checked this on the w5500. If you change the audio output on a blu-ray film from linear PCM to bitstream my amp changes from PCM to Dolby Digital. I have an older Sony AV receiver (dav-s550) that is fed a signal from the W5500 via the SpDif optical out.
