There is conflicting information on how many DMIC interfaces are supported on the Jetson Orin Nano 8GB SOM. Section 1.9.3 of the datasheets says that it supports 3x DMIC. However Table 11 of the Interface Comparison and Migration lists only 2 pins (197 and 195) as DMIC capable. The pinmux spreadsheet shows pin 124 as the only exposed DMIC pin.
Hi, DMIC is no supported. The datasheet and other docs will be updated.
