Horrible digital crackling and distortion over USB

Ensure you are using the most current USB drivers available as they were updated when the CoreOS 2.1 was recently released.

I am. Already checked that, the sampling rate, the DAW settings, everything.

Did you try the safe mode on the ASIO control panel? There are a ton of variables for USB audio related noises/interference. Do you hear the interference via headphones (and or all outputs?) as well? Lastly, have you tried to backup / factory reset and restore the QC?

Tried safe mode. Tried backup and reset.

Distortion only comes over my headphones and ONLY when using the QC over USB, but the distortion is in the signal chain since I am able to record it.

Sorry that you continue to experience these issues. Have you temporarily tried using another laptop/PC to see if the same behavior is exhibited? Otherwise, your only recourse is to continue escalating with NDSP to help you resolve.

I don’t have another device to try it with unfortunately. I’ve been talking with NDSP support for several days now and we’ve run through all of these, nothing has worked. As I said, it has been doing this practically since I got it.

Sorry to hear that! Are you using the OEM power supply? Depending on where you are located, I would strongly consider sending it in for warranty repair and let NDSP diagnose the issue. You don’t hear too much about USB audio noise anymore and cases are getting rare etc.

Everything I am using is what was supplied with the unit when I purchased it. NDSP customer support has suggested numerous things to try to fix it but nothing has worked at all. It just did it again now twice.

Maybe you missed this earlier…?

Edit; My post from a similar topic, and I’ve just spotted someone at the bottom suggesting something to try on windows machines by the looks of it. It doesn’t need drivers on a mac…

Also another post there with the same system as my new one (albeit older OS, I’m on 13.4) so maybe it’s down to the supplied cable? If you see the same numbers as I did in diagnostics, that’s the first thing I’d swap, as it’s so cheap. As I said there, I got a ugreen B to C cable, and it’s not glitched at all since then.

I did in fact totally forget about that, sorry. I unplugged and restarted it and it has stopped, but I’ll remember to do that next time to see if there’s anything going wrong in the unit itself. Also might be worth mentioning that I previously had an Axe 3 which never did this and I still have a 10+ year old Focusrite Saffire 6 USB that still does not do this to this day.

I tried changing the cable, it has not fixed my issue. Checked diagnostics and it seems like inWriteIdx, outReadIdx, outWriteIdx, all collapse to 0 when the issue occurs and USBAudioOutRdWrDistanceAverage goes up to about 500-600. This isn’t consistent though.

Update for anyone reading this…
This has not been solved. I just reinstalled Windows today, totally fresh with nothing on the computer except my DAW, some VSTs, few games, and the NDSP driver. Still getting the same issue. Tried switching to my 15 year old Focusrite Saffire 6 USB as soon as the QC had the issue, just moved the cable from the QC to the S6 without rebooting anything, turning anything off, or closing programs, and the S6 had no issues at all. Moved the cable back to the QC and instant problem.

This is telling me it isn’t a PC hardware issue, but it is on the QC. Also tried factory resetting the QC and running it at stock settings, still had the issue.

is this after DL’ing the new update today? There are MANY hotfixes in it, one mentioned crackling but I’m not sure if it’s the same issue you’re having.


“ An issue leading to output cracking at high signal levels during certain startup conditions.”


I downloaded the new update and latest drivers. It has not been fixed. I also again tried letting the issue start occurring, then swapping the USB cable to my 15 year old Focusrite interface, and the issue stopped as soon as I swapped the cable. Then, I swapped the cable back to the QC and it immediately started again.

This is not during startup and it is not over output. It is only over USB when using the QC as an audio interface. It happens during any audio interaction, such as recording or playback. With or without a DAW. I can be recording, listening back to a recording, listening to random music, or watching YouTube.

I am also experiencing this issue and have given up using QC as a recording interface. Have tried on two separate PCs running Windows 10 and Windows 11, latest drivers, QC fully updated.

@Scottiopause After quite a few emails back and forth with Neural, they have asked me to ship it to them for repair. I just did today, so I can let you know the outcome of it. But you can also email their support as well and maybe get this outcome too

It would be great to know if a repair fixes the problem. I’ll look forward to your update!

I too am experiencing the same problem. As an alternative, I was recording using the SSL12 audio interface.
I wanted to use the reamp feature this morning, but I’m upset that I had to give up due to the same problem.
We suggest sharing the usage environment (Installed ASIO Drivers, OS, etc.,) with other experiencing the same problem.
