Sound drivers: support/rejection of zero value for period
...
SN76489:
The SN76489 chip will produce a note for value 0 - but the driver will reject
this value - but it does allow value $400 - (logically the same) to produce the lowest note
AY38910:
This chip does not produce a sound for period of 0 - so its also rejected
The max value for this driver is still $0FFF
