I tried to use a fully working sketch from my arduino uno on several ESP8266s, but there is absolute no output from the speaker

Code: Select allvoid tone(uint8_t _pin, unsigned int frequency, unsigned long duration) {
pinMode (_pin, OUTPUT );
analogWriteFreq(frequency);
analogWrite(_pin,500);
delay(duration);
analogWrite(_pin,0);
}
