Adau 1467 Input 32/33 does not work

Hi Lorenzo,

I guess the first thing to do is to find out whether the problem is in the input, routing or output. Try to route the signals that go to channels 32/33 to channels 36/37 instead. If you can hear the output, then the problem is in the input or on the routing.

Cheers, heke

Hello,

Thanks for your input heke.

Please also note that if you are trying the mic input with 32/33 then it wouldn't work without pre amplification. Our eval boards are designed for line level inputs, you must need a pre amplification for mic inputs. You need to enable the SDATAIO4 pin for 36/37 inputs but 32/33 is default. it doesn't need any config. So, the issue must be with the hardware/input side.

As heke mentioned, just add some meters into your project and look where the problem is.

Regards,

Harish
