When using Room EQ Wizard (first time user) I'm getting a quiet background hum then a slight pop and it stops. Then when I click "Measure" it hums for 5 seconds then pops......all while the logarithmic tone is going on. If I close the measure window it does it again but stops for a while until I open the "Measure" window again. When I close REW it does it once then it doesn't come back until I open REW again. Any idea what's causing it...or if it's affecting my tests?
