Hey everyone, I'm having a big issue with my Audient EVO 8. I'm so tired of it.
It produces an insane, glitchy noise on every preamp, regardless of what's plugged in, and even when nothing is plugged into it. I thought it was EMI from being close to so many electronics, but I now tested it far from everything, and the noise still happens. I can't open it up because of the plastic construction; there are no bolts or anything.
I tried different ports on my computer, having it plugged in and not plugged in, turning off the Wi-Fi, disconnecting my speakers, and checked that my electricity is grounded, as well as every other thing I could imagine. It happens whether or not 48V is turned on as well, so it just became unusable for me. I don't know if the interface is like this or if it's broken, which means I can't even sell it.
I attached an audio file with the noise.
This is recorded in my living room without any electronics nearby except for my computer (Macbook Pro m1 pro). I tried with a Behringer UMC22 and didn't have this issue, so it's not the computer either.

Sell this crappy shit and buy RME Babyface.

I tried this. The noise happens on every preamp but is specially loud on 1 and 3

 

I tried that too. It didn't get me results either. Every now and then it works better for a few minutes but nothing more than that

 

Move your mouse - does this moving add more noise, harmonics a bit (look at the spectrum)? if yes - this is USB and PC(motherboard maybe) problem, usb power.
Behringer synths thru USB (as midi connection) add such noise (not the synth, I read this noise goes from usb even with moog or other synths). Different cables have various level of noise. Solved by adding ADuM3160 (usb isolator - insert usb wire into this adum then in pc). Removes all the noise and such harmonics. But long use adds huge latency, so it need standalone true midi interface. Don't know how audio interfaces work with adum, compatibility is not for all devices.
Try other cables first. Usb3.0 or higher, type c.....
Have no problems with audient id14 mkII thru usb 2.0

 

RF/EMI from the computer/motherboard. You could probably hear/pick up signal/interference when moving the mouse of making the graphic card work.

 

Sounds like a real defective Device. Warranty?

 

Yeah I'm on it

 

I tried with everything unplugged except for the interface and it still happens, even far from EMI

 

I had the same issue. Firmware I got from their support fixed it. Known issue.
