Does not your computer sound system give you a choice on what to mute and not to mute? Lower right where speaker or whatever is. Click on mixer and make your choices. If your computer is not that modern, then I do not know.Is there any way to disable the sound on the Arkansas Road video ad that plays every time I click on a new thread? I have muted my sound on FireFox but its a PITA to have to unmute it when I need to listen to something else.
