Setting WM8731 parameters

Post by AndreasSteil » Fri Apr 27, 2018 11:29 pm

Hello,
is it possible to set WM8731 Audio CODEC parameter, e.g. to make it use a specific sample rate (BOSR) or the Filters to be used? If yes, where and how can I set the parameters (i.e. to write the relevant registers of the device)?
Thanks for an answer,
regards,
Andreas

Hi there,

If you want to change the operation of the codec, probably the best place to alter register settings is in the codec driver :
