I am trying to run the Adafruit I2S 3W Stereo Speaker Bonnet (with 3W 4ohm stereo speakers connected) with the Nvidia Nx using the I2S0 interface that is exposed on the 40 pin connector:
Currently, I have the following pins connected to the Adafruit board:
12- I2S0_SCLK (Connected to pin 12 on the Adafruit board)
35- I2S0_LRCK (Connected to pin 35 on the Adafruit board)
40- I2S_SDOUT (Connected to pin 40 on the Adafruit board)
Is there any command that I need to run to enable this interface? Do I need to modify the device tree? I tried playing sounds but it does not seem to be working. This is my first time using an I2S interface. It actually looks like the Adafruit board plugs right into the 40pin connector on the NX which is pretty convenient. The sound settings give me the option of playing sound through the “HDMI / Display Port 2” and the “Analog Output”, but neither one actually plays any sound when selecting the Test Sound option.
Thanks for your help!
