[Triton 500] Weird problem with audio cracking when both 3.5 earphones and 3.5 mm mic are plugged

Mido96

My laptop is Acer Triton 500.
I'm using 3.5 mm IEMs and 3.5 mm mic (I don't use any hub/splitter, I use the dedicated 3.5 mm ports).

When I connect both my IEMs and mic, I hear this weird cracking sound in my IEMs every couple of seconds (equal intervals).
I recorded the cracking sound using my phone so turn up the volume: https://anonfiles.com/H8O4PdMbp8/cracking_sound_mp3

I'm 99.9% sure it's the fault of the laptop, not the earphones or mic. Both are quite professional devices and I have tested other IEMs as well (the cracking sound occured with any IEMs I tested).
I also used USB DAC to indirectly connect my earphones to my laptop and it "fixed" the problem but this "solution" is not acceptable to me for a couple of reasons I won't mention here.

I also tried turning on and off many different settings of the mic in windows audio settings but it didn't help. Any ideas?

Try reinstalling the audio drivers in device manager. restart the computer.

Didn't help at all, it actually ***** up some other things I had to google again how to fix.

am sorry for that but its the usual basic procedure. Try to do a bios defaults. press f2 during the startup of the unit. try bios default and save.

Didn't help. I doubt anything software-wise can help. Look how close the ports are to each other. I bet they are not isolated enough from each other inside. Which is kinda ridiculous in a laptop this expensive.
