Yes, I was wondering if the new 'default Track type' was causing an issue with importing audio.

Have you tried to both Open the file in RB and Import the file (Audio-Import wave file)? Any difference?
Like I said, I can't seem to duplicate it here, but I have heard of the issue once before.

Maybe even try right-clicking the file name and choose 'Open with .." then find RB to open it with. Just shooting for anything that may help locate the issue.
