what to do about hum/weird noise?

william074

i've build a new computer, it runs great. got a little static/interference noise from my studio monitors but that's not the main issue right now.

When i open the Maschine software, a weird hum noise starts. I can't really explain how it sounds but i can only hear it when i open the software. My setup is a PC with the Komplete audio 6 mk1 interface and KRK Rokit 5 monitors.

The weird thing is when use my old laptop with the same setup i hear no weird sounds coming from the monitors.

i've searched the whole web for info but can't seem to find anything related to this.

Is Maschine plugged directly in the computer or through USB hub? If the latter, try to plug it directly into computer USB to see if the noise is still there

Maschine is plugged in the computer, but even when my Maschine is not connected the noise still there.

Usually that's a ground loop, in my house the only way to avoid it without buying anything specifically designed to stop it is to use a different wall socket for my speakers and computer, i actually need a cord coming from the hallway to my room, something to do with the electrical phases you got in your home, I'm not an expert tho.

If you unplug your laptop from the wall do you still get the noise?

Prob what @D-One. What kind of audio cables connect your interface and monitors? Are they balanced TRS to TRS/XLR cables or TS to RCA cables?

Laptops are always a pain for electrical noise and a test can be simply to unplug the PSU and run it from battery only to see if the issue still occurs but if the hum starts only when you open the Maschine software, maybe you have an input selected in the software that is opened up when you open Maschine? Could just be pickup on an unused input maybe.

I agree with @JesterMgee and @D-One. If you use different wall outlets, it might cause ground problems... Even if outlets are in the same room. It should not matter in ideal case, but real world is far from ideal and electricity installations may be far from standard....

Also, hum might go from internal circuits of computer... But in that case, it should be heard also if used by other audio programs...

Also, type of wires used between computer and loudspeaker may play role...

If that is just Maschine SW... Might be, as D-One has suggested, that input of soundcard might be routed to Maschine and you hear that hum....

Thanks for all your input,

I was maybe a bit unclear in my message, i only got the weird noise with my new PC, and NOT with my old laptop. I use balanced TRS cables from my monitors to the interface, and everything is plugged in the same outlet.

Is there a way to get into the soundcard driver because i use the asio driver and not the standard drivers from the pc.
