Why is the bm 800 microphone beeping?

Question

Electronics

Hello, in general, there is such an electret Chinese microphone , I received it recently.
At first, I set up recording through savihost and bias, achieved a relative absence of noise when recording games, connected directly to the motherboard. I recently bought (in vain) a dexp 3d sound sound system, it turned out to be non-working, it just squeaked. I connected a microphone to it, then turned it off and removed it. After I connected the microphone back, it seemed to start beeping when recording and the sound processing programs, savihost and bias, stopped helping, I don’t understand what happened. And it happens that the squeak disappears, but it still appears then again, a couple of times after that it was possible to remove the squeak during recording, but it still came back after a while. I don't understand what happened and what to do about it? Whether that sound card interrupted some drivers or something ... I apply an example of a squeak
Athat's what we managed to achieve earlier , well, this is just an example, after more processing there was no noise at all ...
In general, I'm confused, what happened and how to be, where did the squeak come from?

Why is the bm 800 microphone beeping

God, seriously? dexp 3d sound? I could easily burn the microphone by applying too much power via USB.
Buying a microphone for 1,200 and 3 times cheaper usb-sound recorder is a very, very strange idea.

Microphones do not squeak, any "squeak" is the result of a malfunction / poor-quality sound path or excitation as a result of feedback (sound from the output gets back into the microphone - mainly when you try to record with listening through the speakers, the sound goes back to the microphone and as a result of multiple amplification there is a mess :))
1. Do not turn the sensitivity of the microphone to the maximum - the higher you turn it, the more interference and reflections
2. Do not use integrated sound cards, especially since they do not know how to 48 phantoms.
3. Balanced input + high-quality microphone cable.
PS Find any person with a recorder and check your microphone - Zoom/Tascam

These are the pickups of digital components. Turn the cable in the other direction somehow, to the left or to the right. In general, play with it as if it were an FM radio antenna, and you will definitely get rid of squeaks.
