My issue is similar, except that I have W7 installed is on a brand new 64-bit machine. The HDMI output form the GIGABYTE | GV-R467ZL-1GI card works fine, but the SPDIF output from the ASUS P5Q PRO TURBO does not work. ASUS says there are no BIOS setting to change. Also, an external DVD drive plugged into the same SPDIF slot in my Amplifier works, while the optical output from the board does not. The SPDIF device shows as an option under Playback Devices, but when enabled, there is no sound.
