PC thinks my surround system is only 2.1

post #1 of 6
Thread Starter 
Hi,

I have a Yamaha surround system that I have connected to one of my 7970's.

The issue I am having, Is that my PC doesnt recognize the HDMI connected reciever as a 5.1 system.

The display on the front of the reciever tells me it only has a 2.1 signal on its input, but if I turn on my Xbox 360, the reciever recognizes it as a 5.1 audio source.







does anyone know why this is and what I can do to solve this?

PC Checks;

Do you have the speaker settings properly configured in the Windows 7 Audio Control Panel? Is this happening when playing back from one particular application or all of them?

i.e. WMP, Cyberlink, VLC?

Are you using any 3rd party codec packs?

i.e. Shark007, CCCP, K-lite etc?

Receiver Checks;

Does the AV/R detect your HDMI as a digital input?

Is your AV/R capable of passing through or decoding PCM signals?

Here is a screenshot of the signal information recieved by my reciever:


I have installed K-lite codec, I use MPC-HC for the most part, but when I start it up, the reciever display does not change.

I tried looking through the audio settings on my PC, but I didnt find any that let me set 5.1 audio or surround for that matter.

You need to go to the Speaker Setup portion of the Windows 7 Audio Control panel and change the settings there. You'll have one or more of these options; Stereo, Quad, 2.1, 5.1, 7.1 (I'm not on a Windows 7 machine right now so I can't look exactly).

On my Pioneer AV/R - if I set the Windows 7 speaker settings to 5.1 or 7.1 my receiver only detects (and shows) as two channel PCM (even though I'm still getting surround sound - Dolby or DTS doesn't work). If I set the Windows 7 speaker setting to Stereo, then my receiver shows that it is decoding Dolby and even DTS from the PC and I still get surround sound.

My PC is also connected to my AV/R via HDMI - AMD 5850.

I cannot find any Speaker setup page on the audio control panel

Found a "config" button down on the left side, now my reciever shows as 5.1! smile.gif

Control Panel > Sound

Looks like you're still using the TV speakers to me. You need to find your "playback device" set it as default and configure it.

For example:

Edit: Meh too late.
