I use an Windows 10 PC with an audio interface. I connected an Beh­ringer U-Phoria UMC202HD by an USB2.0 port. Via my headphones, I can hear crackling noises. Especially in deep frequencies, the crackling gets louder.

I have tried the following points without success:

  • I changed the interface by an Focusrite Scarlett 2i2 2nd Gen and the same crackling noises still appear. So, the interface is not responsible.
  • I connected multiple headphones with the interfaces. The crackle noises appear with each one. So, the headphones are not responsible.
  • I changed the latency in the interfaces multiple times and could not make any improvements.
  • It doesn't matter whether I connect the device to the USB 2.0 or 3.0. Crackle noises appear less with 2.0 but they are still there.
  • It does not matter whether I listen to music in the browser on Soundcloud or use my DAW. The noises occured with every software I used.
  • It doesn´t matter whether I use the ASIO driver or the driver of the manufacturer of the interface. The crackle noises appear with both drivers.
  • It doesn´t matter whether I change the sample frequencies (44.1KHz, 48KHz, etc...). The crackle noises still appear.
  • The Scarlett Focusrite interface has a button labelled with 48V. When I switch this button on/off, in both cases the crackle noises appear.
  • In Windows, I disabled "Fast Startup" and "Sleep" in power Options and restarted the computer. Here is an article. But it does´n help.

Note: When I record music via the interface and my computer, the crackle noises are not recorded. I only can hear the crackle noises via my connected headpohones when I play anything on my computer.

Who knows a solution for my problem?

    I'm voting to close this question as off-topic because this is an electronics question, and because the solution is unlikely to help anyone in the future. – Carl Witthoft Jan 25 '19 at 15:21

    @Carl Witthoft. Thank you for your explanation. But your voting is invalid. Many musicians are affected to this problem. The instruments are not working correct, so why not sharing this problem on a plattform where are also musicians which have the same problem? – Simon Jan 25 '19 at 17:55

  • Do you get the noises when you just use the computer's built-in soundcard? How about when you use the main audio outs of the interface, rather than the headphones? Any chance of a recording of the noise? – topo Reinstate Monica Jan 25 '19 at 23:56
  • @topo morto: There are no crackling noises when I use my onboard soundcard. – Simon Jan 26 '19 at 15:43
