Hi, I recently bought a new audio receiver, a Onkyo sr608, when my old Harman Kardon died. Everything worked fine on the old system with powerdvd 10 ultra. Now i get no sound when playing DVD's or Blu-rays. I can hear sound from Hulu and my streaming netflix running through to the receiver just fine. I can hear mp3 files and movie files played through Power DVD but no sound from dvd's, just the video. I think it has to be the program and/or some setting I'm missing in the program. I've messed around with the speaker config in powerdvd but it still has no effect.

My setup:

PowerDVD 10 Ultra (full version) 10.0.2325.51
DVD100920-01
TR101125-038
Windows 7 x64
HDMI from my geforce 260 to receiver
SPDIF from onboard Realtek sound card to receiver
Dual Monitor (extended mode)
AGV anti-virus

Any help would be appreciated.
