sound card Is my sound card failing?

[soumyagent47]

Hello people, ok so my problem is that initially my headphones and mic (mine is decent HP H120 headset) used to work good and then all of a sudden the headphones started producing buzzing noise/ white noise/ electric interference and ultimately the static was so much that I gave up on the onboard audio and decided to buy a cheapo usb sound card, which was working fine 7-10 days until today when strangely headphones were fine but the mic is problematic (no bars rising on recording device tab or any other software e.g. - Google voice search, discord in any game) and I think the levels are too low for any program to detect and for some reason I think that it's more of a software problem than a hardware problem although I can just buy another sound card, any suggestions to fix this problem would be appreciated.

 

Thank You.
