    With Windows set to 5.1, you will see “Multi In” on your receiver…this is normal since Windows is outputting 6-channel uncompressed (PCM) sound. You won’t get simulated surround (i.e. Neo6, PLII) because they only work with a 2-channel source.

    Because “Multi In” is the mode that you want to be in to get LPCM 5.1 or 7.1 sound out of your Blu-Rays, give these alternative settings a try:

    In Windows configure Control Panel/Sound for 5.1, then in WMC, set speakers to 5.1 and disable WMC navigation sound effects (in Settings/General/Visual and Sound Effects). With these settings, you may loose the ability to use the simulated surround modes on your receiver, but Blu-Ray multichannel LPCM sound will likely work.

    P.S. Configuring both Windows and WMC to 5.1 may result in HDCP errors in WMC’s Live TV and playback, but disabling WMC navigation sounds seem to get around this problem (I can’t explain why this is).
