This SWI is used to turn the machines internal speaker on or off.
If a machine does not have an internal speaker, or has no control over the speaker power, this SWI will always report that the speaker is on.
On RISC OS 5 this SWI simply calls SoundCtrl_SetMix and SoundCtrl_GetMix to mute or unmute the speaker.
