.aif files broken in new version

[seanbrennan]

version 5.9 does not play my .aif / .aiff files, instead I get high pitched screeching sounds and then it crashes.

Had to revert back to 5.8 where all my audio file formats play smoothly.

Have tested with various playback devices and same result. I'm afraid the new version is already broken and we hope for a fix.
