I am running into some audio issues with my HTPC. When playing recordings in media center, I am only getting sound from the center channel. I am using either dolby pro logic or NEO 6. When media center starts you can hear the tune play through all the speakers. You can also hear the tone when you move up and down through the menus. When a recording with dolby digital is played, sound comes from all speakers just fine.
here is some info on my configuration:
OS: Windows 7 x64
Software: Windows Media Center
Audio/video: I3 2100 integrated video/audio via HDMI
Tuner card: Hauppauge 2250
The HTPC is conntacted to a Denon reciever with HDMI, then from the reciever to a Visio LCD with HDMI. The onboard sound card has been disabled and under sound in the control pannel the Denon reciever is selected. Media center has been set to stereo.
