Audio interference by PC?

I have had the problem for weeks that my studio monitors every 2 minutes for about 3 seconds rushing (no hum), ie. It is a loop. Have the monitors connected to my audio interface via a jack. The interface then to my PC, which is then considered as a power source. The interface uses USB 2.0 and tested it on the pc on USB 3.0 and USB 2.0 and it always comes up with the same noise.

It can only be on my PC or have to do with the power supply, because the speakers on my laptop are working properly. However, when I plug my headphones into the jack connector, this noise does not occur.

Can you help me with this?

That's because of your phone. Try the flight mode from xD

No, my dear. It's not that easy haha

Could be the lack of power.

Hi. You've already started here, right?

Apparently there was no match.

Have you ever checked who or what else in the house rumfunkt?

I had a malfunction in my amplifier here

once up in the apartment of my landlord

an ancient kettle was turned on.

Maybe you have such a troublemaker nearby.

No, it can't be because I tried it on my laptop and it worked there. I think it is somehow connected to the power supply.

These are certainly active monitors.

Do the switching power supplies?

Switching Power Supplies? Ne are each connected by cable directly to the mains.

The power amplifiers in the LS could have switching power supplies.

Post here the exact name of the monitors.

If I remember correctly, you bought the second hand, right?

No new. Have the lsr 308 of jbl

You connect the interface to the laptop? Not the other way around?

I do not understand.

What is the structure of these sets?

It could have something to do with your PC's port search.

If I remember correctly, the PC points at regular intervals or at

Activity of connected devices to the ports.

An example:

I always had a crack on burned CDs.

It turned out to be a consequence of mouse movements. That means,

if I have moved the mouse during the burning process and the calculator

has done something with the ports, this cracking has become known.

Does not matter how rum, whether laptop to interface or interface to laptop.

For me it is independent of any activities. Why port search? Who knows, maybe it's broken on the motherboard

That, for example.
