Hi, I have this Lenovo S410P touch, which has a combo jack. I use my Isurus Dub earphones with it. After some driver updates, my mic suddenly stopped working. I tried plugging it to my phone but the mic still works well. I did a system restore, problem still exists. My internal mic is too noisy so I don't like using it. I think it's a driver problem but checking my Device Manager, everything seems to be in place. Ideas? Any help would be greatly appreciated. Thank you~
