Strange result when testing sound card calibration

Hello,

This is my first time using REV and have experienced a strange result when testing the calibration of the sound card. As it is also my first real post I am not sure about including attachments. My sound card is a Creative SB X-fi. I finally worked out how to calibrate the sound card and the result looked ok. When I tested the calibration the frequency curve was fairly flat but was at 124.7db rather than around 75db.

Any suggestions?

To get the levels right you need to go through the SPL calibration steps I linked, when you do that you use an external SPL meter to tell REW how the levels it is seeing from the soundcard translate to SPL figures. If you follow the steps you should see correct levels.
