No Audio Sound Pioneer VSX421 Receiver - PC


Standard Member
Hi everyone,
I recently bought a Pioneer VSX421-k Receiver and connected it to my PC and TV with a HDMI cable.
The Video works fine but the problem is that I can't get the Audio to work.

My GPU (ATI HD4850 Sapphire) supports both video and audio and the receiver has the HDMI repeater feature.

Is anyone familiar with this problem?

Do you get audio if you connect the PC directly to the TV using HDMI?

Hi clockworks, yes it does, but I think I have worked it out, I need to have the av receiver on first before I turn the pc on, thats what I done lastnight and it worked, I was a bit late so ill try again later to see if that was the problem,
