Some peripherals can be mis-used to produce sound effects...
Cassette Motor Relay
Switching the casette Motor On relay on or off can produce a 'click' sound (done via PPI Port C, Bit 4).
- Works only on 664 and 6128 (which contain a relay for use with external cassette drives).
 - Does not work on 464 and 464+ (which have internal transistor-driven tape drives without relays).
 - Does not work on 6128+ (which has no tape drive connector, and thus no relay).
 
Printer Beeper
Several printers do have an beep function (for example, the Amstrad/Schneider DMP2000 Printer), producing a beep sound on receiving chr(7).
- Works only if the printer is connected and switched on, only if the printer supports beeps, and only if the beep feature isn't disabled (via DIP-switch).
