Can't play DTS muziek files with new computer/receiver setup

(1/2) > >>

4BYE:
Hello,

I bought a new HP computer for our livingroom and installed MC. I also have a recently bought ONKYO receiver. When I played in the old setup (YAMAHA receiver) I could hear the music from my DTS music files. Now I get a static noise. I know you get this when you don't have a receiver that can deal with DTS etc. but this one does. I can not figure out what I'm doing wrong. I connected the PC with a HDMI cable to my receiver and I guess that I must recognize evry signal that is send to it. Could it be a setting in MC or in my driver? I would say it gives the noise so the receiver should deal with it but it should turn it into music... :'(

Thanks for any help.

P.S. I read about same problems on www. Someone mentioned that HDMI signal is only passed through and not decoded and that one should use SPDIF for it to be processed by the (ONKYO) receiver...

Alex B:
What is the sample rate of your "DTS music" files?

If it is 44.1 kHz you may be out of luck if the sound device in your HP computer is not capable of transmitting bit perfect 44.1 kHz signal through HDMI or SPDIF. Many integrated sound devices support only 48 kHz and the Windows mixer "hepfully" resamples the signal and thus destroys the DTS code.

What kind of setup did you use previously? Did you have a separate high quality sound card?

It may also be a driver issue. If you want to transmit unaltered DTS signal through a digital connection you must use a setup that bypasses the Windows mixer.

Practically that means using an ASIO driver (integrated sound devices don't usually support ASIO) or the so called WASAPI exclusive mode (which is only avalable on Vista and Windows 7).

Hello Alex,

Thanks for your reply. I had some trouble with my DVD too, but fixed that by putting some changes in the FFDShow options in the CCCP settings. I think I marked the AC3 - DTS - AC3 Encode Output under S/PDIF after that I got the AC3 and DTS sound on my receiver.

I checked some files and have 44.1 kHz - 16 bit files. I also have some .dts files but cannot see what the bitrate is.
I have a HP 3742nl slimline computer connected with HDMI to my ONKYO 876 receiver. It should decode through HDMI according the help-desk.
This is my first VISTA computer, so that's new to me.

I can not find what kind of soundcard it has. There's a Realtek Driver with settings for SPDIF and HDMI.
Hope this helps a little...

On Vista, try changing the playback in MC options to WASAPI, as Alex suggests.  XP would need ASIO and the driver.  See this link in the Wiki for starting points:
