Many thanks John, very helpful. The 16 bits in device control made the difference as all others were as they should have been. Regarding the increase in volume to 100% in soundcard control, does this then stay at 100% or revert back to 50% after the measurement?
Anyhow, I got it working and the curve was exactly as expected.
I then did an automatic sweep of the sub and that was not
I set the target level at 77.6 but achieved a peak of something like 36 db. The graph was just a mess with both peak and dips off the graph and only reaching a third along the way. Is my room really that bad or am I (again) doing something wrong?
