Every time I plug in (or off) my headphones (even white iPhone ones), Mac OS X locks up for about 10 seconds, and then works as normal, and even displays the beach ball. Not everything locks up, as I can still switch screens, etc, but I think the Finder does.
Initially I thought this was related to Flash, as the Flash Player would stop working, but this happens even when the browser is closed.
I don't have any audio related apps installed.
Does anybody have any ideas of what could causing this, or tips on how to track down the problem?
