Your input is set wrong. Looks like it is set to stereo. Should be Left Only.
What's wrong with only using the left input channel while setting the input to stereo?
The meter is only showing activity on the left. Go to I/O:AUDIO and change Input 1 Mode to LEFT ONLY.
Also, you are clipping or very close to it. In your AMP block, lower the LEVEL a few db (3? 6?)
Am I getting this right?The input level calibration will be wrong by a factor of two.
