Help with REW setup

[Barak]

Hi, I think there is a setting that I am missing or do not understand. I tried to calibrate 2 different sound cards. In both, I get the following message:

And the sound card measurement comes out really strange. I would appreciate your help. Thanks in advance.

The sound cards I tested with are: EVO 8, Focusrite Scarlett 4i4 G3

It is impossible to know what the issue may be if we don't know what your input and output settings are. Please provide screenshots of the preferences at a minimum.

If the levels bars shown is with nothing playing and just the loopback cable connecting I/O there's something really strange happening there.

Please include the following information:

- what soundcards you are trying to calibrate
- how you are doing the loopback
- what the input/output settings are (as per @sam_adams) - include a screenshot please
