Humming when using microphone
Hi guys!
I have a Sony Vaio F laptop, that I have connected to its AC power adapter. I also have a analog headset, and whenever I talk through the microphone, the person on the other end hears a buzzing noise. Is there any way I can fix this issue?
I have bought an external sound card to see if that would fix the issue, but it did not. I also wanna note that when I UNPLUG the AC adapter and run straight off the internal battery, the humming goes away.
The AC Adapter I am using is 2prongs and it has a ferrite filter on it.
Is there anything I can do to fix this issue?
Its really bugging me!!!
Thanks!!!

More than likely the result of a defective or low quality headset. Especially if it's happening on an external sound card.

Is there anything else connected to the laptop? (ethernet, video, printer?) A hum is almost always caused by a ground loop between devices that are plugged in to the wall. In this case the power supply is completing the connection and causing the loop. I've experienced this quite a bit with Apple laptops because of the way they wire their power supplies, but never heard of it happening with a Sony.
Can you flip the AC power plug or is it keyed to only go in to the recep one way?

Thanks for the reply!!!
I can switch the prongs, yet it doesn't help.
The only thing that is plugged into the laptop is the AC adapter and a logitech USB mouse reciever
