Yes, I saw I2S support as well as for external audio codec chips, but nothing for the on-chip Class D.
Are there any other supported processors that have on-board audio that I can use as a “template”? I’ve run out of ideas of what to search for!

Before I dive in and find some time to create a driver from scratch, have I missed something? Documentation on audio support in general seems rather lacking so any pointers in the right direction would be appreciated (even just a suggestion of another processor with similar capability I can use as a reference). TIA, Tim.
