I am a UK user and I have just installed my NSZ-GS7 supplied by Sony through their pre-order process.All is working fine except that I cannot get any sound from SD TV programmes or SD recordings on my Humax Fox Sat HDR. Sound from HD programmes, HD recordings and the Internet (You Tube, Sony Entertainment Network etc) is fine.I have the box connected between my Humax Fox Sat HDR and Panasonic TV via HDMI and to my Panasonic Home Cinema system via optical cable. I have cut the Home Cinema out of the equation so it's just TV, set top box and the NSZ-GS7 and that makes no difference. I am thinking that it must be a setting issue on the NSZ-GS7 or a hardware, software or firmware problem with the NSZ-GS7. Can anyone help please? Thanks.
