See prescaler for the speaker and motor driver:

timer_set_prescaler(
	    TIM8, (rcc_apb2_frequency / 24000000 - 1));
  • Use macros instead of 24000000?
  • Why the -1?
  • Are all the timers connected to rcc_apb2_frequency?

Use the oscilloscope or digital probe to check the actual PWM frequency.
