USB Audio Synchronous Mode on KL27 AN13364 - …
https://www.nxp.com/docs/en/application-note/AN13364.pdf
In the USB audio speaker example within the NXP software development kit (SDK), the asynchronous mode is used to realize the audio synchronization between the USB host and the device. The device provides the real transmission rate of the device to the host through the feedback endpoint, such that the host can adjust the actual transmission rate.

The USB interface is very well suited for transport of audio ranging from low-fidelity voice connections to high-quality, multichannel audio streams. Many applications from communications, to entertainment, to music recording and playback, can take advantage of audio features of the USB. The Audio Device Class specification standardizes audio
Usb audio protocol - NXP Community
https://community.nxp.com/t5/LPCXpresso-IDE/Usb-audio-protocol/m-p/561080
From reading the internet, I think what is missing from this code is the ADC_Init ADC Audio Initialization,ADC_DataIn ADC DATA In Callback,ADC_DataOut ADC DATA Out Callback. But no example for these so no clue what I should do here as well. I found some reference to this in updated code, but not keil code, CooCox code in a H file.

Even though I'd prefer if the host-support was a generic/native component in Zephyr, I'm totally fine with a NXP/i.MX RT specific host driver. As long as we can do "otg" device/host switching with dual usb-interfaces, we're good.
