Hello @rexrothppc,

Good to hear you find a workaround.

For more information, you could check the following information about the MQS that could be useful:

RT10xx SAI basic and SDCard wave file play - NXP Community and,
FLAC7.1 Implementation and Audio Quality Measurement on RT1060 and CS42448 Audio Card.

Best regards, Raul.
