Receiver not playing sound from PC

[Ciper]

Hey,

So I've double checked and the speakers are all connected correctly and are all working. I've connected an hdmi from my computer's graphics card output to the receiver. There's also the hdmi running from the tv to the receiver, and a toslink connection between the computer and the receiver (because I read that you can't get surround sound quality from the graphic card hdmi output).

Now when I go to the computer hdmi source, all I get is picture, no sound. When I go to the toslink source, I get sound, but only in the subwoofer and two front speakers. Is it possible to be on the hdmi source so that I get HD quality picture in my tv, but have the sound streaming from the toslink? And furthermore, how do I set up the receiver to distribute the sound to the 5.1 system, not only the two front speakers and subwoofer? The sound is likewise not working at all when I have the ps3 connected via hdmi to the receiver, which leads me to suspect I need to change some settings in the receiver... but unsure what they are.

Let me know if anything I said doesn't make any sense.

These are the parts I'm using:

Graphics card: Gigabyte 275 gtx
speakers: Klipsch HD 300
receiver: Pioneer VSX-1019AH-K

Thanks!

Adjust your audio setting in your playback devices window, win7. Or buy an ATI card and trow away the toslink cable.

Try setting your screen resolution to 720p or 1080i/p. For some reason, a lot of receivers won't play audio over HDMI unless the source is set to a standard HD or SDTV res.

Yes, toss away the toslink. Digital is digital.

From what I have seen on the net his card only has a DVI output so he is using an HDMI to DVI adapter.

He should also read his receiver book.

For the record, my ATI card feeds my receiver via HDMI and supports all the HD audio standards. It works.

The settings on the receiver seem to all be fine, it's set to output the audio to the 5.1 surround system. Strike my comment about the PS3, the audio works perfectly for that.

The only problem is no sound when the computer is selected as source. I do have an HDMI output from my graphics card, no adapter, so there should be audio without needing the toslink as well. I just don't know how to set up the hdmi connection to output a 5.1 sound to the receiver. Any thoughts? On my computer there doesn't seem to be an hdmi output at the playback list of the sound settings, either, and no apparent way to set it up using the graphics card menu.

 

[NutBucket]

In control panel you have to set the default audio device to HDMI. Then it will route all the audio to the HDMI port.

 

[Ciper]

The HDMI isn't listed there for some reason.

Would it be possible to output video through hdmi and audio through toslink to the receiver and have the receiver play them both in the same channel? Or is that a blasphemous union?

> hdmi = no sound

Does the GTX have its own audio chip, or do you need to run a cable to the soundcard or motherboard digital out pins? The first generations of nvidia with HDMI did not have their own audio chip.


> When I go to the toslink source, I get sound, but only in the subwoofer and two front speakers.

With many soundcards and motherboards you'll only get stereo 2.0 out from everything except DVDs or other movie files that have a pre-encoded 5.1 audio track.

You need "Dolby Digital Live" software to get 5.1 audio from real-time sources like games over optical or coax (or HDMI passthrough).

The newest video cards with onboard audio chips either do that encoding or just pass 5.1 as PCM audio.

 

[Ciper]

No, I have to run a spdif wire from the graphic card to the motherboard. I don't think it has its own audio chip, so I guess it's of the first generation.

I am using a dolby digital live software right now, but it's still the same; only front two speakers & sub working.

I think it might be a software thing or something to do with my onboard realtek sound card, but I honestly don't know. Any tips would be muuuch appreciated.

You need to assign the hdmi and the optical to a named source in the receiver setup. Eg setup the dvd input in the recever to look at hdmi1 for video and optical 1 for audio. Set these acording to the jacks they are physically connected to on the back of the receiver. Then in windows you need to open sound settings by right clicking on your sound icon in the system tray and select playback devices. Select spdif and open its properties. From there you can tell windows what audio formats to send over the toslink. You. Can test dolby and dts from this menu and your receiver should show the digital icons on its display.

Typed on my tablet so let me know if i skipped anything or if its unclear at all.
Edit
Im really good at not reading the last post... id skip passing it through the card if you can. Not that it hurts anything. I think you just need to do the second step of my post and you should be good to go.

Yeah my Onkyo TX-SR805 will only operate at 16:9 or there will be no sound, only video, which is a pain if I just want to play some music out of the hdmi port of my laptop. My Pioneer and Yamaha receivers don't have this problem.
