you caould have given a bit more inf about the error but of noteng happends and only an error sound comes than that is a verry strange error... you could try playing in a browser or deleting the .minecraft folder (to accsess it go to the serch bar or go to run and type in %appdata%) and try deleting it. you could allso try re downloading minecraft you may have an out dated luncher. the file myht allso be corupted or oyu may have a minor virus
