    Hello,

    There are a few things that you can check to figure out what is going on. First, you could go to the register map and look at your mute register to make sure both channels are not muted. You can also check your digital volume to make sure the volume is not set to 0. I did notice your output crossbar has the I2S config set incorrectly, so I would recommend to change it back to default. It would also be worth knowing what the EQ file and audio source are. I could be that your EQ makes it so whatever frequency being used for testing is being attenuated.

    Regards
