Having trouble finding this info -
I'd like to know if ReplayGain is recognized by the CoreFLAC codecs. There is an entry in the Registry for ReplayGain, but I can't find any documentation on how to use it in Windows Media Player. (Listening to tracks in WMP, there is no evidence that ReplayGain is working.)

The registry entry for CoreFLAC is at HKEY_CURRENT_USER\Software\CoreFLAC\Source
