We have just had to have our My Sky box replaced. I am looking at the audio settings that the Sky guy left us with on Sky's 'Audio & Language Settings' screen.
The Sky box is connected to an upper-market Sony AV receiver via an HDMI cable. The receiver is driving a 5.1 speaker arrangement.
The 'HDMI Digital Audio Output' setting has 'Dolby' or 'MPEG/PCM' options. The SPDIF Digital Audio Output setting has the same options. I am not at all sure what the best settings are and would welcome advice. Am I right in thinking that the SPDIF setting is irrelevant if we are using HDMI?
