Well, IMHO, the fundamental problem is that there is no logic to
select the beep device in the input layer. A few line of code to

calls aren't good. Also, note that there are hardwares that still
beep even when the beep volume is set to zero. So, you may get a
situation that you can't disable beep tone.
