Jetson Nano and I2S audio module MAX98357

I am trying to connect the audio module MAX98357.

I connected the module pins according to this:
LRC → pin 35
BCLK → pin 12
DIN → pin 40
GND → pin 6
Vin → pin 2

Then updated my Jetson gpio config by:
sudo /opt/nvidia/jetson-io/jetson-io.py
and choose adafruit sph0645lm4h configuration

Then configured the mixer:

amixer -c tegrasndt210ref cset name=‘I2S1 Mux’ MVC1
amixer -c tegrasndt210ref cset name=‘MVC1 Mux’ ADMAIF1
amixer -c tegrasndt210ref cset name=‘MVC1 Vol’ 12000

And tested:
aplay -D hw:tegrasndt210ref,0 chirp.wav

But no sound is playing
