Is there a way to disable sound output on the Apple IIe from Applesoft Basic? Can't seem to find this in any of the documentation or online.

Update: Found this

From http://www.calormen.com/jsbasic/reference.html

POKE 49200,0 — toggle speaker (no-op)

But that doesn't seem to work...

In this case, to "toggle" the speaker means to move it from one position to the other. To make a sound, you repeatedly toggle the speaker (by poking that address) at a particular speed to make a sound of a particular frequency.

There is no way to turn off this functionality using software. The easiest way is to pull the jumper connecting the speaker to the motherboard.

  • It depends on who is accessing the speaker, though. The corresponding peek or poke can be removed or redirected to achieve silence. Commented Jul 6, 2018 at 19:16
  • Yeah, I remember we often had to pull the jumper as the Apple II cases seemed to reverberate badly at exactly the frequencies the speaker put out. This was like someone scratching their fingernails down a blackboard :-) In the end, we did a school project that "extended" the speaker into a separate enclosure, less prone to painful effects.
