[Solved] Can't get 5.1 on HDMI

I just installed 7 on my media pc, everything it working fine EXCEPT NO 5.1 audio over my HDMI
the computer is an Acer AX1200-B1602A. It has that High Definition Audio Device as the sound card. and it has a Ge-force 8200 and the video card.

I am plugged in through the HDMI cable and it is getting picture and sound but it isn't 5.1. The receiver doesn't even show what sound it is. (it usuly has a diagram of speaker to show what audio channels it is receiving).

Under sound in the control panel it show 4 devices one is the standers headphone ports (analog) the other is a coaxial (it clams it can do DTS and Dolby digital) then i have 2 devices that say they are HDMI, "Realtek High Definition audio divice" and the other is "Digital Audio (HDMI)". I only get sound from the Digital Audio but they both say they can only do stereo.

I have tried every driver I could find, nothing has changed

Back when i had vista on it it worked fine, and the AMP said it was getting 5.1.

Any ideas?

Try to configure the speakers under sound properties.

Right click on speakers icon next to the clock.

Select Sounds from the list

Then select Playback tab in the top,

Right click on Speakers

then select Configure Speakers

Which 5.1 speakers are you trying to connect?

I am connected to a Pioneer Elite VSX-01TXH Amplifier, it is actually 7.1 sound but i only need 5.1 because i am just using it for TV

There isn't any Analog video or sound connected. just HDMI, an esata hard drive and mouse and keyboard. That is all that is connected

Thanks

I don't think my Amp supports that, it only has HDMI, optical, coacial, and the standart Left and Right audio connectors, to input the sound. As far as i know

O good idea i haven't run anyupdats yet. Totaly forgot about that


Oyeah I forgot to mention there is a "PCI Simple Communications Controller" That doesn't have a driver. Would that be causeing any problems?

.

I am using all Klipsch speakers
For the Left and right Front i am using the "Forte FB"
here is a pic I found of them But mine are all black.

For the Sub i am useing a MX-125

For the center is am using a KV-2

For the left and right side speakers i am using KSF-S5 Surround Speaker

for the left and right rear i am using SS.5 Surround Speaker

most of them are old speakers i think the newest ones or the Rear speaker set. But it sounds really good.
