Buzzing sound when listening through wired headphones on Laptop

[minemarcius]

Hello,

I've been having this annoying electric buzzing sound when my headhpones are plugged in to 3.5mm. I've found that when I touch the bottom of the chassis or unplug from power buzzing stops, so it must be a grounding issue, my question is if any of you have any suggestions on how to ground the bottom of chassis? Thanks

You could solder one end of a wire to the rear IO, then have an eye loop on the other end that you put a case screw through. What case and mobo do you have?

This happens on my Laptop, so this solution probably won't work. I'm looking for some quick & dirty solution, that I could use in those cases when grounding is messed up.

Yes it is a grounding issue. I don't quite remember but I think it was due to interference in the wall circuits.  I'm not sure what can be done apart from using USB or possibly try another outlet.

Outside of fixing it properly internally (again, by soldering a wire from the headphone jack to a good ground point on the board or chassis) there isn't much you can do.
