No digital sound out of external sound system
I have a GA-EX58-UD3R Rev 1.6 mobo in a PC connected to a Samsung PS63C7000 3D TV via HDMI and by Stereo Analogue, Coax and Optical to a Yamaha RX-V567 receiver/amplifier.
The mobo runs the Realtek audio system supplied with the mobo, which has 5.1 Analogue outputs, coax and Optical out.
On the receiver I match the HDMI input to one of three Audio inputs; Analogue (AV5), Optical (AV4) or Coax (AV3). Sound only comes out of the Analogue connection, which is stereo only.
When I look at the sound on the PC it appears that a signal is being sent to the receiver. (through a spectrum analyser)
I tried reinstalling the sound drivers for the mobo, with no luck. I don't have a spare sound card with Optical. I tried replacing both the optical and coax cables.
When I plug the PC into a set of PC speakers it works fine.
I saw this post .. digital sound issue, but I had already made sure only one sound option was connected at any one time.
oh, I am running Win7 x64 Ult.
Any ideas?
