Hi ; I just set this #define in the project:

define SOUND_ENABLED 1 // Enable SOUND

define I2SAUDIO_ENABLED 0 // Enable I2S sound

define PWMAUDIO_ENABLED 1 // Enable fallback PWM audio (when no I2S)

define AUDIO_I2SPORT 0 // I2S_NUM_0 or I2S_NUM_1 (I2S_NUM_0 is USED BY COMPOSITE VIDEO)

and directly connect a little smartphone speaker thruth a NPN CMS transistor (+resistor on base) on the defined PWM pin.
