Not yet. However it has become a priority now that I'm running Windows 7 on most of my systems.

 Chris, you sound like a good person to ask. I am having volume problems using my digital connection to my receiver. I'm using a Realtek integrated card in Windows 7 Home Premium with the Coax digital connection. When I watch DVDs and blu rays or watch tv the volume is fine. When I try to listen to MP3s, the volume fades out in the loud parts. I went into my hardware and under the digital connection, it shows the green volume bars staying constantly to the top. When I lower the volume it still sounds faded in and out and still shows them maxed out. For testing purposes, I hooked up a stereo jack to my receiver and it sounded fine. Do you have any ideas how to correct this in the digital connection as I don't want to switch back and forth?

DVD's etc are going to pass through unaltered as an AC3 data stream. MP3's are going through the operating system PCM mixer first and then going out as a PCM digital stream. Make sure all the windows enhancements such as loudness equalization are disabled (Control Panel -> Sounds), and disable any similar features in your media player (graphic equalizer, sound enhancements etc).

 Thanks, it seems to have worked with one minor thing is it doesn't seem to put out an LFE or subwoofer channel.

Hi Chris, any luck on getting it to work with Windows 7? I'm having the same issue. Thanks!
