Need Help With Settings

[pmforester]

I think my continual questions have gotten lost in the bottom of threads.

This is an audio settings question

I have a Sony BPD-S350 and a Yamaha RX-V663 receiver all connected via HDMI 1.3 cables.

On my BD my settings are as follows for audio.

Audio Output Priority = HDMI
Audio (HDMI) = Auto
BD Audio Setting = Direct
Audio ATT = Off
Dolby Digital = Dolby Digital
DTS = DTS
48kHz/96kHz PCM = 48kHz/96kHz PCM
Audio DRC = Auto
Downmix = Normal

No factory settings were changed on my receiver except speaker sound levels.

When I play a 5.1 Uncompressed (48kHz/24 bit) audio movie my receiver displays PCM Is this the correct display?

When I play a Dolby TrueHD audio movie my receiver displays the Dolby digital symbol. I am pretty sure the TrueHD symbol should be displayed.

What is wrong with my settings? Why does the Dolby TrueHD symbol not show up??

Please help. Thank You!!
