Cant get SPDIF output to work with receiver

post #1 of 6
Thread Starter 
Sound card on my PC is a Sound Blaster SB1354. Receiver is a Yamaha HTR-5640. I have the 5 of the 6 speakers hooked up (no rear center) and they work correctly through the receivers audio test. I have the sound card hooked up (PC out to DVD in) to the receiver via an optical cable and the default playback device set to SPDIF-out. The test option through windows plays through the front left and right speakers but when I run the audio test in the Sound Blaster control panel I get nothing at all. If I play audio in VLC, WMP, act I get left and right audio and the sub but that's it. What am I missing here and how do I get audio out of all 5 speakers?

With the 2.1 working via SPDIF (through VLC at least) the front control does absolutely nothing either.

OK, I'm retarded, I had the receiver set on stereo. Have 5.1 working but the front panel still isn't working.

I'm pretty sure you have to have either analog connections or use HDMI from your video card to your receiver in order to get 5.1 sound, unless you are outputting either Dolby Digital or DTS compressed audio. I think coax/toslink doesn't have enough bandwidth if it's an uncompressed signal, say from a game.

If you are trying to send a DD/DTS signal from a movie or DD live game, then I don't know.

Recon3D, right?
You have to switch the Dolby Digital Live encoding ON from the "Cinematic" settings tab.

The encoding allows you to pass 5.1 audio through optical. Without encoding only 2.0 PCM audio signal can pass through optical.
Movies are always pre-encoded to DTS.

And I would guess that the reason why the test in recon3d control panel doesn't work is because it only tests the analog outputs.
I recommend to check the manual/guide. The last part explains how you can send the analog audio to the optical output.

Yep, and I didn't get a lot of time to test it before work but enabling that seems to have it all working right.
