Please help me! I am really struggling with this one. I built an HTPC and am unable to get 5.1 over HDMI to my receiver.


I have:

Windows 7 Media Center - OS

NVidia GT 430 - GPU (HDMI out)

ASRock H55M/USB 3 - Mobo

Onkyo TX-SR605 - Receiver


In the NVidia settings the resolution is set to include audio out. The sound settings include the receiver but only offer 2 channels. Haali media splitter shows 5.1 channels of audio but the receiver is only outputting 2.0.


I can't see what I'm missing. Can you help?


Cheers

Actually, if you go to control panel-device manager-sound video and game controllers and delete all the audio devices 7MC will figure out all the audio devices you need and install them. I would not recommend installing Realtec. I removed it and let 7MC figure it out.


I would suggest you right click the speaker icon on your task bar and see what playback devices you have and how they are configured.


I would also double check the AVR and make sure it is set to correct input and double check the display and make sure it is set to the correct input.


Are all you devices HDCP compliant. If Microsoft PlayReady decides you do not have digital rights management you won't get any sound...of course you won't get any video either.

You sort of have two options, AFAIK.


1) You can set up your filter/codec pack to use passthrough. This will take any multichannel content and send it straight through to your receiver. Right now the filter is decoding the content and passing it through the Windows audio system which is set up for 2.0 sound.


2) You can set up Windows to use multichannel sound. To do this, go to Sound in the control panel, click on your HDMI device, then hit Configure.

Thank you all, for your responses.

Any advice on which filter/codec pack would be a good one to use?

I don't see an HDMI device only my receiver name with a TV icon. It says I only have 2 channel audio. Speaker Config only allows stereo.

Yes, they all are. I am getting 2.0 sound and channels from 7MC.

so you are going from your computer to your receiver to your tv, right?

that is how it is suppossed to be hooked up.


other than that, make sure you have updated drivers for your nvidia card.

Yes. 7MC ---> Onkyo ----> Sharp TV all via HDMI


NVidia drivers are the latest and I have tried 2 different cards (GT430 and GT9800)

Are you playing live TV with 7MC or a movie with 7MC, commercial software or with MPC-HC? Do you get the same results with different players?

Does your AVR bitstream, (HDMI 1.3 and above)? If so try passing the audio through to the AVR. I right click to playing media, go to settings-audio and select the type of audio I want.


Is your setup using your TV's speakers?


How many speakers do you have?

Playing live TV, playing Videos via MediaBrowser (WMP) and also tried via KMPlayer and VLC. Same results.

Yes, it is 1.3 or above. I do just want to pass the audio through to the AVR but can't seem to make that happen, windows gets in the way.


I am not using my TV speakers - I have 5.1 speakers via the Onkyo AVR

Does your AVR post the format it is playing? Does it say PCM or Dolby Digital or Stereo?

Did you right click the speaker icon on your desktop, go to the playback tab, click on your AVR, click on configure and set up your mains, surrounds, and center speakers and test them and hear each speaker sound.

Yes but the audio channels say I only have stereo, I cannot setup my surrounds. There is no option.

So you clicked on the speaker icon, then your avr under playback devices, clicked on configure and you were not permitted to set up 5 speakers.


If so, you are beyond my technical skills, but there are many who know more than me.

Yes that is correct. Thank you so much for your help.


It seems to me that either windows or my hardware is getting in the way. I just can't seem to get the multi-channel audio out to my AVR via HDMI (or any other method)...

The only other thing I could think of was that perhaps your AVR is telling you computer that only two speakers are attached. So, recheck your AVR speaker setup.
