I don't know if you still need this answered but I had the same problem, and it doesn't look like it was answered here.

1. Right click on your sound icon and open sound settings.
2. Sound > Advanced Sound Options > App volume and device preferences
3. Pull out or plug in your power cord and Realtek HD Audio Manager should appear
4. Set to Zero and enjoy blessed silence

I'm currently using Acer Aspire 5. Everything is working fine. Audio and mic are OK. Except for the annoying beep when I plug in/unplug the charger.

So here is the fix that I found that just gets rid of the annoying beep. (The audio and mic still work.)

1. Uninstall the Realtek Audio driver (restart required)
2. Download the Realtek (driver only) from the Realtek official website.
3. Install it and SHAZAM!!!! The annoying beep is gone.
4. One last thing. You need to prevent the driver from automatically updating.(Google it.)
