Audio comments in Word X

[Liza]

I have a document originally created in Word XP on a PC. It contains
both text and audio comments. When I open the document on a Mac
running OSX and Word X I can see the text comments, but when I try to
open the audio comments, I get the error message:
"Word cannot edit the Soundrec"

Is there any way I can listen to these comments in Word X?

Thanks,

Liza
