Hi
Our project use TDA4vm k3-j721e
audio codec : tlv320aic32x4
~# aplay -L
null
Discard all samples (playback) or generate zero samples (capture)

tlv320aic32x4, davinci-mcasp.0-tlv320aic32x4-hifi tlv320aic32x4-hifi-0
Default Audio Device
~# aplay -D sysdefault:CARD=tlv320aic32x4 /usr/share/sounds/alsa/Side_Left.wav

My device tree about audio is as below:
We use AUDIO_EXT_REFCLK0 for audio mclk and mcasp6 for i2s.
Could this pinmux AUDIO_EXT_REFCLK0 for mclk ?
Does my settings be correct or something missed ?
