I've had the Yamaha 667 av receiver and Sony 370 Blu Ray for over a year now and it has never given HD sound. It is setup via HDMI and the Yamaha connects to a LG 37".
I can get DD and DTS from DVDs and on Blu Ray the titles are in Dolby Digital, I can also get Dolby Digital on foreign soundtracks, but using the Sony 370 I can only get either PCM or 'no decoder' using either Blu ray audio downmix on or off. I have tried every conceivable combination in the amp and blu ray setups but still no HD sound.
If anyone has one of these combos could you let me know what your setups should be, or if anyone has any other ideas else that I could try.
Many many thanks
