Neo Air I2S interface without MCLK pin

[meisam]

Hi all
Any idea for Neo Air audio interfacing with popular DACs that needs a MCLK (256 * fs) ?
Many popular DACs like WM8731 needs a MCLK in excess of SCLK and BCLK.

As you know if needed to control the audio volume on a DAC it should be clocked by MCLK
for internal delta-sigma processor.

You can use the Matrix - NanoHat PCM5102A module.The module uses TI's DAC audio chip PCM5102A and NS' low-noise, ultra-low dropout LP2992 regulator. PCM5102A's sample rates up to 384kHz and its resolution is 32-bit.PCM data style is I2S.

With thanks of your advise , PCM5102A does not have any control like volume attenuation or mute . I need a DAC with
control option.

We didn't ever use WM8731 with this I2S channel on H3 board. And has no suggestion on that.

Thank you
