I understand your point, but as a user if I want to control a feature of an application I expect that control to be in the application, not some central sound daemon. I would think the default user behavior when looking to control the sound of an application would look first in that application not at some upper level. I agree with the poster you are responding to, the problem with browser sound is with the plugin/browser, not some central sound control. I can't tell you how often I right click on some flash application thinking there will be a volume control in the context menu. There should be a control in that context menu, that there isn't is a problem with the application.
