I’ve made some sample recordings of the pops at different sample rates and buffer settings, here’s a link: I will update this main post with things that I’ve tried, and if there’s something that definitively fixes it. If anyone has any idea for what I could do to improve the situation, that would be great. If anyone’s very interested in the way it sounds, I can record it on my phone later. I would record what they sound like, but for that I would have to solder up a weird connector right now, and I don’t know how this interface responds to chaining it’s outputs directly to itself. Finally I also tried it with my phone (Cubot Quest) through the USB C OTG port on there with a little adapter. There however, I suspect it was CPU bound, as it’s a very old laptop (2GB of ddr2 and an intel core centrino duo) with limited cpu power. On my linux laptop it had a bunch of pops and crackles as well. I’ve also tried the interface on a couple of other systems. 192Khz instead of 44.1Khz) the pops where of a audibly higher frequency. What’s quite interesting is that at a higher sample rate (i.e. The UMC404HD is connected to a usb 2.0 port, and changing it to another port (3.0 or otherwise) didn’t change anything.Ĭhanging the buffer size did change the amount of pops and crackles, where a smaller buffer size generally caused more pops and crackles. So, even after changing the settings a bunch of times, with sample rates from 44.1Khz trough 192Khz, and buffer sizes from 8 to 8192 samples, I still get pops and crackles. Note: Because I’m a new user I can only post one picture, will update with more once I become a normal userĪll other in and outputs have the same settings as out 1-2 properties. Ram: 2x 8GB Ballistrix Sport DDR4 3200 MHZĪs for my current audio settings, I’ll write them down and include some screenshots. I’ll start with an overview of my system.:

After doing some googeling, it seems like it’s an buffer starvation issue. Anyway, I’ve had the Behringer UMC 404 HD for a little while now, however I’ve had a fair amount of pops and crackles.

Some of you have already heard my complaints a little bit ago on the last livestream (17th of may).
