 Tremendous amount of noise in your impulse response. What does the impulse response look like when you measure a simple loopback cable? This will tell us if the computer is capable of a proper reading.
Always set the graphs to logarithmic - not linear.
Do a response with the sub only and the mains shut off. That way we can see if it tracks a decent target.
Always test with the receiver in stereo with no effects or surround modes on.

Something to do with my receiver and True HD audio made the power in my house go out twice possibly. The first time I had just switched audio to True HD. The second time I was turning down the volume about 10 seconds into the movie. Could be some sorta strange coincidence also. When I turned it on it had gone to a different input selection. I think I need to reset my 3 breakers (two dedicated circuits) to the theater every month much like we are supposed to for the hot tub. Or I am just loosing my marbles. Now that I know the left output works for the mic I went back and re-calibrated using that. The before results were read using the left with the mic but my auto-setup was done using the right on accident. I used the right because it would not give me a ambient noise error. I ignored it this time and the results were much more sensitive. It set my speakers to large. I will redo the test tonight and watch some movies to compare the difference.
Also. Yes I had it set to dolby digital not stereo. I will try with the mains off as well. Crossover is at 50HZ. I will also set the graph to logarithmic as soon as I figure that out. the button pictured was not shown in my version and I had downloaded REW many months ago so I will download the latest version as well. Thank you for the tips.
