First of all, I don't like sounds (because I play a lot of media), therefore I have all system sounds disabled. However, whenever I'm using Remote Desktop (with the remote system muted), I get beeping sounds coming through my stereo.
For example, while using RDP, if I'm in some text editor with pages of text, and I scroll up really fast to the top, the smooth-scroll still has some work to do although it's already at the top. So instead of just stopping the scrolling, it seems RDP decides to make repeated beep sounds (although remote PC is muted).
This started happening in the past few months or so, it must have been a result of some update. Both systems run Windows 7 Ultimate.
How can I stop this from beeping?
