PWM Audio — ESP-IoT-Solution documentation
https://docs.espressif.com/projects/espressif-esp-iot-solution/en/latest/audio/pwm_audio.html
The PWM audio function uses the internal LEDC peripheral in ESP32 to generate PWM audio, which does not need an external audio Codec chip. This is mainly used for cost-sensitive applications with low audio quality requirements. Features ¶ Allows any GIPO with output capability as an audio output pin Supports 8-bit ~ 10-bit PWM resolution

The PWM method would be good for Morse Code but not much for fidelity, whereas an audio transformer has a relatively wide frequency response in addition to impedance matching and, of course, isolation. Option B if you need fidelity would be a ADC and DAC on either side of the optocoupler. Like Reply M Thread Starter M0RFD Joined Nov 7, 2011 3
Audio using PWM, what is the principle behind it ...
https://electronics.stackexchange.com/questions/239442/audio-using-pwm-what-is-the-principle-behind-it
How does PWM do that? The audio signal that contains a spectrum of multiple frequencies is still just an audio signal that can be sampled by and ADC and recreated by a DAC. Providing the sampling rate used is higher than twice the highest audio frequency then all is good. A DAC that uses PWM techniques is no different.
555 Audio PWM Apmlifier | Full Circuit with Explanation
https://www.electronicsforu.com/electronics-projects/555-audio-pwm-amplifier
In this 555 audio PWM project, we explore its use as an astable multivibrator. The ubiquitous 555 timer IC handles audio signals in its own pulse-width modulation (PWM) way. Here, the 555 IC works in astable mode. The switching frequency can be varied from 65 kHz to 188 kHz. Selection of PWM frequency depends on the amplitude of the input signal as well as …
