Hi, This is my very first time having a expensive audio system. I got it 2 days ago, setting it up was easy. But i've noticed some audio delay in games/movies on my PC. What can cause such issues? HDMI doesn't seem to be affected, only optical cable. I've got a Creative Sound Blaster Recon3D PCIE connected to the receiver. I have looked in all the settings on the receiver and soundcard, but nothing does seem to have effect on this issue. The sound comes like half a sec later, it looks very strange and it's very annoying.
