I have a Yamaha 361 av,when receiving bbc HD. the speaker indicater only shows 2 speaker output ( ie stereo ) Linked via TOS lead. when playing dvd or ps3 it shows 5 speakers as for 5.1 surround.Does this indicate no surround sound from my virgin box on HD . anyone
Firstly, ensure you turn HDMI audio override on in the V+ box's settings.
All HD channels use Dolby Digital apart from ITV, but not all content on these channels is encoded with full blown 5.1. Some of the HD content and upscaled simulcast programmes only posses a stereo soundtrack so you'll not see a 5 or more speakers illuminated all of the time and only see this when the actual content or program is encoded with such.
