If it's not clipping, then @jsalerno277 identified my other thought, a missing/bad DC coupling capacitor.
The 95% chance of fixing this is to use a cheap-o USB DAC instead. And by cheap I mean $20 or so.
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.

Thanks. I am not using a headphone amp or DAC. I am connecting my PC directly to my integrated amp using the 3.5 mm headphone/earbud audio outlet using a 3.5mm to stereo RCA adapter cable. If I plug my ear buds into the PC, the "static" is audible. If I play a PC system tone through my stereo, it is crystal clear. So my thought is, I have a setting in REW set incorrectly or my PC’s sound card just can’t play the sweep without distorting. PS. I played the sweep on the PC using earbuds and the PCs built in mic without any distortion (so with the MiniDSP mic unplugged) and sample rate set to above 48kHz so there is come sort of conflict with the USB mic. |
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. |
