Use This call can be used to read the number of different sample rates that are supported by the 16 bit sound system. This value can then be used to enumerate the available rates by calling [[Sound_SampleRate 2]]. h4. Notes This SWI should only be used if [[Sound_Mode 0]] indicates that 16 bit sound output is supported. h4. See also * [[Sound_Mode 0]] * [[Sound_SampleRate 2]]
