Needing a bit of advice. Have recently purchased a Sony HT-AS5 home cinema system to seriously improve my television sound quality. I've connected the Sony system up as described in the manual and via HDMI cables connected both the TV and PS3 to it. The PS3 does seem to work fine through the home cinema however nothing I do seems to work in getting the normal TV sound through it!! Any suggestions? I think going via optical cables may be the answer? Please note i'm only using the inbuilt freeview TV signal in the Toshiba TV and not any kind of sky box etc.
