Why doesn the TrueHD, DD+, DTS-HD, or DTS-HD MA icon light up on my receiver?
Likely you receiver is not receiving the TrueHD, DD+, or DTS-HD bitstream. This does not necessarily mean you are not getting HD audio. There are two methods of transporting HD audio over an HDMI link (see method 3 and method 4 above). Using HDMI v1.1 LPCM output the player will decode the bitstream from the disc to LPCM. It is important to remember that decoding is a 100% digital process. The player will then output the LPCM via HDMI to the receiver. The receiver is getting the full resolution audio it just has already been decoded to LPCM so from the receiver’s “point of view” it is receiving LPCM. The player will display LPCM, Multichannel PCM, PCM 48/24 or something similar. Using HDMI v1.3 Bitstream output the player will take the compressed bitstream and send it to the receiver. The receiver will decode the bitstream to LPCM internally. In this case the receiver’s input light will display the format being decoded. To bitstream HD audio requires an HDMI v1.3 player (HD-XA2, HD-A35
