REW issues - popping, static in frequency sweep output.

Hi All,

I'm using an HP Win 10 Pro, headphone jack out via RCA adapter to the amp and a MiniDSP calibrated mic.

I've read all the help files and adjusted the sound card output to 16 bit which helped but did not eliminate the popping/static noise in the test sound. In my set up the sound card cannot be calibrated and I've adjusted everything I can find. 

Has anyone experienced the same problem and solved it?

 

Thank you.

Two things to try.  If using a laptop, un plug the power supply.  Sometimes these create ground loops and noise.

The other thing is to turn the output down.  You may be clipping the headphone output.

@erik_squires thx Eric laptop is not plugged into mains and I have tried turning the output down to as low as 25%

PS  I use the laptop for conf calls everyday and no issues with audio, also the noise is present with headphones in so it’s not the audio cable
