Final Cut Pro X

Ok this is probably another easy question.

I am doing a video project in Final Cut Pro X.

I have used 2 cameras.
Canon 60D at 720p 50fps
Canon 500d at 720 30fps.

When viewing all my clips in the explorer/event library they play back fine.
As soon as I drag a 60D clip to timeline it seems to be about a semitones out of tune (lower) any ideas what's causing this? And how can I get it to play back normal in timeline as I need to sync it to music.

I have also tried to conform the clip at 100% normal & preserve audio bit it's still slow...
Only slow in timeline , plays fine in event library

Ok my audio sample rate on 60D clips is 48 but others are 44.1 is there a quick way to make it the same?
