You can keep playing a dummy sound in the background to force it to stay active, but then the whining noise will be constant. The trackpad has buttons, but with very poor precision. Web camera has poor quality. It doesn't work with Cheese (confirmed with Manajro too), so you may like to try with other software like VLC or guvcview.
