Correct, Apple normally does not read anything in these discussions. In fact they sometimes (maybe a lot of the time) regard these posts as just rants with no viable foundation of any real problems.
However, I am in contact with a senior tech, who is in contact with the engineers, and I know for a fact that he has looked at this thread because he did it while I was on the phone with him. He's been on vacation because of the holidays so I assume our communication will continue when he returns.
I would suggest, for those who asked how to contact Apple, call Apple tech support at 1-800-SOS-APPLE or 1-800-767-2775, and somehow get to a senior tech. You need to get past the person who answer the phone as they best suited for problem like, you forgot to plug your computer in. Once you have a senior tech, reference this thread, which is #3388112, or give the url of the thread, which is https://discussions.apple.com/thread/3388112.
It's time to "occupy" Apple about this issue. 🙂
As I said in an earlier post, my self, and lots of you said that the beta version worked great and didn't have this sound issue. So if we can all suggest to the senior tech that the engineers just re-release the beta version as an update to this current version, that would be the simplest, quickest way to solve the issue.
