Right Ear Very low on my PC "only"

Electricity went off & then came back, after that when I tried to complete my work I found out the right ear cup wasn't making any sound "when I tested it it's just very low" I thought it was dead then I unplugged it and try on the phone with the 3.5 mm jack and it's just fine, I also tried it with the USB plug on another PC and it worked, just on PC the right ear is super low like it's dead, I tested all my USB ports and they're working fine, what could be the problem ?
