Why doesn the True HD logo appear on my receiver? when playing b/ray through hdmi cable SONY STR-DG820?

Are you asking why the "TrueHD" indicator light doesn't come on when you're playing a TrueHD soundtrack?





A receiver won't decode TrueHD unless the Blu-ray player sends the TrueHD soundtrack bitstream via an HDMI cable. So make sure your player isnt' doing the decoding. If so it will be sent to the receiver as uncompressed multi-channel PCM. If the display says "Multi-channel PCM" then that's probably what's taking place, so tell your player to send audio bitstream and the Sony will handle the decoding....





Unless you have a PS3. PS3s can't send HD audio bitstream. The decoding takes place in the PS3 and is sent out as MPCM, which is exactly what decoded HD audio is.




It depends on your player. The light on the receiver should only show TrueHD when [a] you're playing actual TrueHD material, and [b] the player is sending over as an untouched TrueHD bitstream.





So it depends on your Blu-Ray player. For example, I have a PS3. The PS3 will play TrueHD just dandy, but it does the decoding itself, and sends over an uncompressed 8-channel PCM bitstream to the receiver. In fact, it does that for every format, so you never get any of those feature lights on the receiver. But you don't need to worry about the formats your receiver accepts. That's why I have a STR-DG720... no use for TrueHD in the receiver if it's being handled by the player. It's all digital to digital.. the sound is identical, either way.
