I'm hoping somebody can offer some tips here, as I'm thinking that this is related to Windows 7 and not necessarily hardware.
I've hooked up my PC to my Marantz SR8001 receiver, via the ATI 5870 video card HDMI connection that is hooked into the VCR1 HMDI port on the receiver. I'm able to get sound through the system, however I am not able to adjust any sound properties (equalizer settings) in the actual Soundblaster X-Fi sound card settings/properties program on the PC. I tried hooking up the sound card directly into the receiver via a 3.5mm to RCA jack adapter that was plugged into the sound card digital out port. I tried the auxillary ports and a few others on the receiver but could never get any sound to come though, which is why I resorted to running the sound through the video card HDMI port, along with the video. I checked various settings, tried a different RCA cable but couldn't get any sound. I'd really like to be able to control the sound card properties in the PC that reflect through the receiver, is there a way to do this?
