I returned my QC; my new FM9 is arriving today
I had that issue for years and could not get rid of it until lately. Definitely no hardware issue! So if someone has the same problem, this might be the solution for you as well:
When on Windows 11, the priority of the NeuralDSP ASIO process is set to “normal” by default. I noticed by chance that the same ASIO process of my Focusrite Interface is set to “real-time” by default. And here is the solution: Just set the priority of the Quad Cortex’s process to real-time and the robotic sounds are gone (for me). You can do that in the task manager, just right click on the running ASIO driver tool, show more details and on the next screen right-click again. Then set priority to real-time. Never ever had the problem again and before the QC was completely unusable as an Audio Interface.
It seems to be a Windows specific problem of the drivers, never heard of it for Mac users.

Re this
I’ve been having this issue SINCE I BOUGHT THE DEVICE.
Nothing I tried fixed it.
Every PC had this issue, every version of Windows.
NDSP provided 0 support.
Shit out of luck here bud. I am so mad that they made 0 attempts at addressing this or fixing it, you can see the COUNTLESS posts about it.
P.s,
This driver thing didn’t work for me
This mixed with bloatware running in the background can cause these issues. Dell support assist and tech hub both have to be turned off in Services on PC if you have a dell or alienware.
