I have 4 channel microphone array and would like to connect to the jetson nano. but with no luck so far

This is spec of the microphone:

Things i did:

  1. configure pinmux through jetson-io successfully (mono recording works great)
  2. Configure the I2S interface for DSP-A mode
  3. Configure the i2s fsync width to 0.

Hi irmir10,

We haven’t verified any microphone array, you may use the forum search function to see if can find similar cases as reference.
