Hi to all,

the schematic on this page is wrong ... udioRecord.

The PDMIC interface is mono as explained on page 2194 od the SAMA5D2:

The Pulse Density Modulation Interface Controller (PDMIC) is a PDM interface controller and decoder that support
mono PDM format

so it's unuseful to wire two PDMIC microphones and the state on L/R line is non important. It records always on the same channel.
