Functions
int	audio_clock_set (uint16_t freq_value)
	Set the audio clock frequency. This function configures the audio clock to the specified frequency value. The frequency value must be within the range defined by APLL_FREQ_MIN and APLL_FREQ_MAX. The function will adjust the frequency to fit within this range if necessary.
int	audio_clock_init (void)
	Initialize the audio clock. This function initializes the audio clock system, which may involve configuring the necessary hardware components and ensuring that the clock is ready for use. This should be called before any other audio clock functions are used.
