I had the same problem. I disabled the 2-3 sharp beeps on resume by
system --> preferences --> power management
or from the terminal type
gnome-power-preferences
Then uncheck 
Use sound to notify in the event of an error
under the General tab.
On my system I think the beep has something to do with a UVC error on
resume:
uvcvideo: Failed to query (135) UVC control 1 (unit 0) : -32 (exp.26)
The webcam works well though.
Hope this helps?
