Hello,
I would like to ask if there is already a firmware version that supports the audio interface for the EG800Q module. In the last version of hardware design, I only learned that the PCM interface is under development. Thank you very much for your answer.
Hi @koudeto7 ,
Try to ask it to the moderators, or @herbert.pan-Q
Herbert know a lot, he is the best person that you can ask such questions.
Have a good evening! 
Yes, I know the same as you, currently it only supports PCM
