The 74C14 are single-input gates, so you can't use gate logic
to turn the oscillator on/off (I presume, as you've not described
the oscillator circuit). You could send the AC from the oscillator
through a resistor to another 74C14 gate and ground the input
of that 2nd gate with an NPN transistor (and so also ground the
AC via the resistor). That would give you "1" (sound off) "0" (sound
on) control at the transistor's base
