I'm having problems getting DTS and also Dolby 5.1 sound from my Pioneer VSX 920. I have a Popcorn Hour C 200 and Oppo Digital 970 attached to the Pioneer with only HDMI cables. I tried playing a movie's DTS track of a DVD image file that was stored on the Popcorn Hour's hard drive but the display on the Pioneer listed the input signal as PLIIx. I believe when I selected a Dolby Digital 5.1 soundtrack it displayed the Dolby icon with a "D" to the right of it which is correct for a 5.1 soundtrack.
However, when I tried watching a movie using its DTS soundtrack (Saving Private Ryan) on my Oppo, there was no indication of any type of digital input and the sound coming from the speakers was definitely not surround sound. I haven't had a chance to check the settings on the Oppo but was reading the manual regarding HDMI output and noticed it said:
"HDMI Audio: To select digital audio output from the HDMI port. The options are:
Multi-Channel - Digital audio output via HDMI will be multi-channel PCM format. The
Down-mix setting in the Speaker Setup Page will affect whether and how multi-channel
audio content will be down-mixed to stereo. When this option is selected, compressed
audio bit streams will decoded by the DVD player.
SPDIF - Digital audio output via HDMI will be the same as the SPDIF (digital coaxial/optical
audio) output. The SPDIF setting will affect whether 2-channel PCM or raw compressed bit
streams will be carried over via HDMI. When this option is selected and SPDIF is set to
Raw, the TV or HDMI A/V receiver must decode compressed audio formats. (Copyright
protection on some DVD-Audio and Super Audio CD discs may prevent audio output via
HDMI with this setting.)
Off - No digital audio output via HDMI."
With the "Multi-Channel" the DVD player will be doing the decoding according to the settings in the Speaker Setup Page and the only surround sound option I noticed on that page was "5.1CH - This mode enables 5.1ch decoded analog audio output. The number of actual output channels depends on the disc."
The SPDIF option sounds ideal because the processing is done by the receiver however I have no digital coaxial/optical outputs going from the DVD player to the receiver as I thought HDMI could handle the DTS signal as well as Dolby Digital 5.1. Is that not the case? Or are there other settings I should be changing either on the Pioneer or the media player or DVD player?
Thanks in advance for any info you can provide!
