Disable volume adjustment sound effect while audio is playing When there is currently no audio playing, the 'blip blip' sound effect is useful to know where the volume is currently set.  But when there IS audio playing, you don't need the sound effect, yet is plays anyway.  It is annoying, especially if you are using your computer for a presentation, or music at a party, etc.

Has anyone found a way to disable the volume adjustment sound effect for when audio is already playing?
Hold down the Shift key when clicking the Volume Up/Down keys to disable the volume adjustment notification sound.
