Hi @mhilt ,
RT MQS is using the SAI3 as the interface, then it can output the medium quality audio. About the document, the RAM MQS chapter 37-39 is a good document.
About the code, please follow this document:

Create an internal case, and in the case content, write assign to kerry zhou, then I will send you the RT1050 MQS code through the email privately.
Thanks a lot for your understanding.
Best Regards,
Kerry
