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.

@erik_squires are you driving loudspeakers directly?

I don’t understand. How else would I get a sweep test tone from REW installed on my PC to play through my speakers but via my integrated amp? 

btw the popping noises have nothing to do with connecting to my integrated. The popping is present on my laptop speakers/ear buds when USB mic is connected and goes away when I unplug the mic.

My first thought is a bad connection or a bad mic. Have you tried a different USB port? Tried a different USB cable? Contact cleaner?

P.S. Are you using the ASIO driver or the java? I had issues with the java driver.

My first thought is that you only have one USB root in your laptop (that's a USB design limit).  So the USB mic is conflicted with every other USB device hanging from your USB root.

Do you know what version of USB you have?
