I found this rather old but unanswered message in my archives.

I think there is no audio package available that can play a sound and is 
"embedded" for Windows 7. The point is that the "new" wmplayer does not 
provide any appropriate command line flags. Audio packjages typically 
rely on the fact, that you have an appropriate player available and use 
the one that comes with the OS as the (in this case less appropriate) 
default.

Hence the recommendation is to install an appropriate player that works 
with Windows 7 without warnings and then tell the audio package to use 
that one.

In tuneR, see the help pages ?play and ?setWavPlayer for details.

Best,
