mp3 22050 Hz plays twice as long

I imported an mp3 sound file into the Project View. If I double click it MS Media Player plays it fine 33 seconds. If I click the play button in the Inspector View/Preview section the audio plays for 66 (01:06:00) seconds. The ending 33 seconds is just silent sound. It should play for 33 seconds.

The sample rate is 22050 Hz.

I have reproduced that behaviour in the FMOD PlaySound example. Generally this would indicate a problem with the encoding of the file. I opened the file in Audacity and reencoded it and it worked properly for me after that.
