Audio crackles

Hi,

I have purchased and installed a brand new Focusrite Clarett 8Pre USB audio interface. Recently it started to produce crackling noises both when recording and playing. Before going further let me specify that I have a dedicated PC for my studio, that has been optimised for music production. Although it is not very recent, its specs should be more than enough to allow a smooth operation (Win 10, i7-4770K @3.5GHz, RAM 32 GB, 2x SSD).

I have tried various sample rates and buffer size combinations. The higher the buffer size, the less crackles I hear. However, I need to be able to work at 48 KHz with a total latency under 10ms, which I believe should be entirely manageable with the gear I have. I used a cheaper audio interface before (Roland Octa-Capture) and I never experienced any crackles, and had better latency values.

Any hint on what I should try in order to improve the situation?

Here for the gear
 

Which DAW software are you using ? It's usually software but you have checked cables etc haven't you ?

I'm using Reaper, latest version. Cables are good. It is really crackles and pops, typical noises when you try to decrease the buffer size in an attempt to reduce latency but your computer can't handle it. Except in my case I'm working at 48k, 128 samples, with an i7 @3.5GHz, 32 GB RAM and a fast SSD, so there's really no reason I should be hearing this.

I just picked up the same interface. No problems running at 32 samples.
Also using Reaper. Windows 10, I7 7700k, 32 GB ram, M.2.
I'm curious as to what your problem could be. Have you checked your DPC latency?

This is likely your computer, and would depend on its components and many other factors.

Ok but is there a way to narrow down the culprit?

Download and run the free Resplendence Latency Mon. Should help in troubleshooting. Run it on the basic PC without the Focusrite unit first to make sure the PC is OK.
