Hi! If you go to youtube there is a video that includes a little bit of reading from the audio edition (I think), if that helps any. I would link to it but I think that's forbidden.
Search 'The Legend of Sigurd and Gudrun' there (youtube) and it should come up however. Not the book trailer, but a version uploaded by ANeilsonHC on Apr 7, 2009, for example.
Or I would think the following link is alright. If not sorry.
Two videos should appear on this page. The one on the right has the bits of reading.
