Unfortunately that method does not work for every person and every case. As stated by HTC, they designed the shutter sound to be on all the time and if your phone is operating any differently then it is not operating correctly. If your phone is not operating correctly, or if you want the power to make your own decision on whether to have a camera shutter sound or not, be sure to let HTC know.
I think this thread needs a poll, so people can weigh in on how they feel about camera shutter sounds. Maybe if enough people place their preference we can use it as evidence for giving user controlled shutter sound options.
