No Playback on MacBook (loud click instead)

I don’t know if you saw it but I posted more detailed suggestions at Can't get any sound, just crackle - #7 by Gale_Andrews in reply to your post there.

The possible Audacity issue on MacBook Pro is that you can launch Audacity without interfering with system sound, but if you play something in Audacity then Audacity playback just clicks. If you then play audio once in QuickTime, it will just click. Play the audio a second time in QuickTime then it will play and so will Audacity.

I don’t know if playing a file in iTunes has the same restorative effect as QuickTime.
