I'm encountering a weird problem. I've got my old PC running for browsing purposes its P4 HT on Intel D102GGC2 mobo. recently i purchased new headphones...when i plugged them in i was astonished that the rare audio-in panel is just routing sound through one channel. And there's a continuous hiss noise on the other left side of the earphone. The headphone is working flawlessly on my other PC(C2Q) and on my mobile as well. I've tried different speakers aswell but they all end up giving sound through right side. I've updated the drivers and tweaked everything and concluded that its not a software problem rather a hardware prob. The hiss and distorted noise keeps on coming from the other channel. Help me a way out of it.!
