here's a link how it sounds https://vocaroo.com/i/s0bDaMuYqz68. I had issues with my jacks, couldnt get a microphone working after trying everything, buying a new sound card etc... Now I got a USB headset, everything works, my voice is hearable but there's a constant beeping, pulsating background noise that is very annoying for my friends and I can't really use it, tried different USB ports... what could it be?
