It happens that I just have upgraded my graphics card to a GTX470 then connected it as follows:
GTX470 ==(HDMI)==> KDL-40HX700 ==(TOSLINK OPTICAL)==> STR-DB930
Here after called setup (1)
The reason why I need the setup to be in this way, is because I enjoy the post-processing done on my Sony TV (MotionFlow 200Hz => HIGH & Film Mode => Auto1) and like to keep them on. If I were to feed audio separately directly to my receiver i.e.
PC SOUND CARD ==(TOSLINK OPTICAL)==> STR-DB930
GTX470 ==(HDMI)==> KDL-40HX700
Here after called setup (2)
I would loose the perfect AUDIO/VIDEO sync. This is because the post-processing on my TV introduces a 100-200 ms delay to the video signal compared to the audio signal when the sound signal from the PC is not passed to the TV together with the video on the HDMI cable.
Now my problem is as follows; I can have perfectly both DD and DTS sound on my receiver having setup (2), but why can I have only DD sound and not DTS sound on my receiver having setup (1)?
I downloaded and installed the Core AVC codec and AC3Filter on my PC, then ticked SPDIF passthrough for AC3 and DTS formats; and set output format & rate to "Do not change" + "PCM 16 bit" + "Use SPDIF". I was expecting to be able to playback DD and DTS movie files using Windows Media Player on my TV (SONY TV-1 set as my default sound playback device) with setup (1) and have both sound formats playback on the receiver, but it turns out that I can't get DTS working.
Then I noted that under the SONY TV-1 sound properties I have;
Max Number of channels: 2
Bit Depths: 16-bit & 24-bit
Sample Rates: 44.1kHz & 48.0kHz
Encoded Formats: Dolby Digital
So I started searching internet and found this forum, I then tried lots of the different override inf files of post #1, all sound properties changed, but I still did not manage to get DTS sound with setup (1). I also used MonInfo to create an inf file using the SNYEE01 Full Real-time display ID for my TV and then add the extension bloc from a 5.1 receiver like the ONKYO HT-R380 and install that as an override driver. But all without success!
Then in the asset information report given by MonInfo about my TV, I noticed the following;
CE audio data (formats supported)
LPCM 2-channel, 16/20/24 bit depths at 32/44/48 kHz
AC-3 6-channel, 640k max. bit rate at 32/44/48 kHz
I have a feeling that given that my TV does not support the DTS format, it is not capable of passing the signal through to its Optical Out connector, and that is why the receiver does receiver DD but not DTS from the TV (in setup (1)).
My big question is; if that is the case, then how come when I test the speaker configuration of the SONY TV-1 sound device with a random override inf file installed which enables 8 channels and all 3 sound formats (DD DD+ DTS), I still don't manage to hear a sound out of my speakers other than L and R? I would expect them all to work since the test signal is simply then PCM 48 kHz, not say DTS!
Could somebody help me please? Master Tulli?
