The Thingy:52 also has a speaker, but this is driven by PWM interface and an amplifier, with the audio quality this gives. Using the I2S interface should work well, and should be easy to implement with the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/i2s_example_loopback.html">I2S example</a> in the SDK.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
