while pressing command c , it is making sound

In that circumstance, if you use the menu Edit->Copy, do you also hear a sound or not?

If you do Command-V to Paste, do you also hear a sound?

Is the sound the one that is set in System Preferences->Select Alert Sound?

Also in System Preferences->Sound, do you have checked the box for "play user interface sound effects"?
