Audio Kontrol 1 high pitch

Hello.
I saw someone on an OLD thread asking about a problem he had with his Audio Kontrol 1
I have an old Audio Kontrol 1 Soundcard.
When I connect it to my PC and try to record something with the microphone, when I play it back, I hear a high-pitched noise in my recording. (doesn't matter which DAW I use)
I have an old I3 7th generation and I used Audacity for it.
I thought it might be the mic or cable, so I tried replacing the mic, the mic XLR cable, and the USB cable from the soundcard to my PC. Still, same problem occurred.
But, when I connected the sound card to my old I5 4th generation laptop, the high pitch noise was not there.
So I guess it's a PC-related problem but I can't find what's the problem.
By the way, I connected my Synth keyboard to the other line input, and it's the same when I play back what I recorded.
I attached a sample to this thread
