        Hello,
        We are using the IDC7x7 DK1 and we connected our logic analyzer on the PCM/I2S/SPDIF header next to the module.
        I configured reset the module to:

        AUDIO=1 1
        AUDIO_DIGITAL=0 44100 64 00100100

        Unfortunately we can’t see any signal on the I2S data and clock lines after an HFP(SCO) connection is established. After switching back to analog we can use the Headphone/Mic jack just fine. Do we need to place special jumper on the board or do additional configurations?

          When I look at your configuration, you have AUDIO_DIGITAL=0 44100 64 00100100, that means you are in Slave mode (the first 00 in 00100100). So you need to change it to 01100100 to change it to Master mode and the module will generate the clock. Please note that PCM is not implemented yet (soon) and SPDIF is not available on that module.
