Many people don't know how to turn the PC speaker beep lower or off.
And IMO its volume is too high by default.  It can distract an entire
classroom.  That's 30+ people per beep.

OK, can we make that an option on the Options menu?  Should I file a
new bug to request that?

Fair enough.

How do we remove them on a case-by case basis?  The beep from pressing
C-g perhaps is possible to remove individually.  But how about the
"End of buffer" one you get when you try to move the point past the
end of the buffer?  That is just a beep on (error).
