Acer Aspire One 722 – disable charger beep in windows 7

There is one and only working way to disable PC speaker beep in Windows for Acer Aspire One 722 (Acer AO722):

  1. Install original Conexant audio driver (otherwise PC speaker option won’t be available!)
  2. Go to Control Panel > Sound > Playback Tab > Speakers > Properties > Levels Tab
  3. Mute PC Speaker

There is also the disable Beep alternative. The same as above applies – it won’t work unless you install the original Conexant audio driver (for both x86 and x64).


Good luck!
