Ah, perfect! I was using v1.7.1 I'll install the latest nRF Connect SDK and give it another try! Thanks for the quick answer!

[quote user=""] Is there an example somewhere?[/quote]

Check out these samples (use NCS v1.8.0):

https://github.com/nrfconnect/sdk-zephyr/tree/v2.7.0-ncs1/samples/drivers/i2s

As well as the i2s tests:

https://github.com/nrfconnect/sdk-zephyr/tree/v2.7.0-ncs1/tests/drivers/i2s

This bare metal sample is also worth taking a look at if you want to understand the i2s from the bottom up:

[quote user=""]If I2S is not supported through the Zephyr RTOS, is there a way to access the legacy I2S drivers for the nRF52840 from within the nRF SDK5 / Zephyr / VS Code development environment while still having access to the rest of the Zephyr OS for other uses?[/quote]

Support for the Nordic i2s using the Zephyr api was just added: https://github.com/zephyrproject-rtos/zephyr/pull/34251/commits (NCS v1.8.0), so there is no need to use the NRFX drivers.

Best regards,

Simon

Make that nRF Connect rather than nRF SDK5.
