Team,

Could you share me the PCM5121 initialization I2C script? It is set as VCOM mode and no need to configure DSP. We tried several setting but still cannot get output. 

Regards,

Nic

    Hi Nic,

    Here are the commands to initialize the PCM5122 for VCOM mode, and to disable the AMUTE.

    w 98 02 10 # Set standby mode

    w 98 41 00 # disable auto-mute

    w 98 00 01 # Set page 1

    w 98 08 01 # enable fast VCOM ramp

    w 98 09 01 # enable VCOM

    #Wait a few milliseconds for VCOM to power on

    w 98 08 00 # disable VCOM fast ramp

    w 98 01 01 # enable VCOM mode

    w 98 00 00 # set page 0

    w 98 02 00 # exit standby

    VCOM and AMUTE.cfg

    Thanks,
    Paul
