Ultra+ lowering output signal

I use this in a minidexed setup, and it is literally plug and play, so that is fantastic, but unfortunately the signal is too hot, so there are a slight saturation in the general output sound…is there any way/code to lower the signal?

Hi, I do not know well minidexed, how did you configured it for the ULTRA?

Ok. Well it uses whatever sound device is on the i2s channel. So i dont install any specific driver.

ULTRA needs I2C codec commands before able to play an I2S stream
