Hi I have tried to connect my Sony nsz gs7 with my sky HD box but Dolby digital will not pass to the receiver. My set up is as follows: Sky HD box (Samsung) fed via HDMI in to Sony nsz gs7 HDMI out from Sony nsz gs7 to onkyo receiver Optical out from sky HD box to Sony nsz gs7 HDMI out from onkyo to tv I have basically set the sky HD box to output Dolby digital. There is no pass through option on this box. Everything else seems to work OK except known Dolby digital channels being heard via the receiver. Does anyone know how to get this fixed?
