Mac OS X 10.5.2 Special Report: Clicks from speakers

Some users are reporting a strange issue where unwanted clicks are emanating from the speakers under Mac OS X 10.5.2.

One reader writes:

"Since the upgrade to 10.5.2 I get clicks through my speakers (audio quality with a subwoofer) that weren't there before. For example just before the Sent mail sound there is a click, as well as before sounds in iChat, when Quicktime has opened and audio is about to start, playing the first song in iTunes, etc."

Weirdly, this is an issue that last appeared under Mac OS X 10.2.5 in 2003. Conspiracy theorists note the inversion.

At that time we noted: based on a number of reports, the problem is resolved for some portables when external power is connected. Some users have connected the issue to individual applications including Microsoft Office, Final Cut Pro and XSounds, but there does not appear to be any discernible pattern among the group.
