As some may know, I and a few other users have been trying to solve an issue with the UniBody MacBook's and MacBook Pro's speaker popping noise after an amount of inactivity. I tried some more troubleshooting today, and installed Windows 7 in VMware Fusion. I went ahead and tried to see if the speakers still clicked while using Windows in a virtual machine, and they didn't. This means that the issue is specific with Mac OS X. Even more specific, system files/.plist files. Does anyone know where are the locations of every single .plist file on Mac OS X. I know there are some in ~/Library/Preferences, but are there other locations? Also, I was reading a post where someone went to the Apple Store and they removed "Unnecessary audio files" and that person has not had speaker popping ever since. Any ideas on this? Any other ideas on solving this issue? Thanks a lot!
