Audio does not insert from media library

Oh dear.

I cannot insert my little .mp3 test audio into an album. Even the autoplayer option with the audio already present in the post) does not work.

I tried deactivated all the other plugins. Still no success.

Want to take a look? http://www.alamuze.net/just-a-test-ignore/?preview=true&preview_id=1653&preview_nonce=ad4a350ebb

The other plugins have since been activated. But it makes no difference.

Thanks for any help you may provide!
