ChibiOS uses GPIOv1 for the F103, which only knows of one alternate function.
On 'larger' STM32s, GPIOv2 or GPIOv3 are used; with them it is also necessary to configure `AUDIO_PWM_PAL_MODE` to the correct alternate function for the selected pin, timer and timer-channel.
You can also use the Complementary output (`TIMx_CHyN`) for PWM on supported controllers. To enable this functionality, you will need to make the following changes:
