Using a .wav file as source for a Media Player

I can import a .wav file and use it as a source in a Sound Cue. Likewise, I can create a Sound Wave that references a Media Player, and use that to create a Sound Cue. However, most of the formats that Media Player accepts are video formats. Is it possible to use a .wav as the source for Media Player?

I just added some missing audio file extensions to the WMF player plug-in. You will have to sync to Master or merge the following commit: 8b1c79d

However, please note that audio streams are not fully implemented yet and may not work correctly. We will try to sort that out this month though.
