Recently my less than year old laptop has started making crackling noises that have made listening to music less than bearable. I researched what the possible problems were and after cleaning out my jacks and conducting a few tests on why it was crackling (such as checking diagnostics) I thought that it could be nothing other than a faulty sound card. I tried to update the drivers but it did no good. Today I had support come to my apartment and replace the motherboard because the sound card it attached. At first it seemed like the problem was fixed, but now, about 6 hours later i've noticed it again. It seems to happen more with low tones (but it could just stand out more because the crackling is high pitched). Does anyone have any idea what the problem could be?
The headphones are completely fine, I have tested them on my Ipod and they don't have the crackling. The only possibility I can think of is a software problem but I can't say I know too much about hardware.
