Hello all, My first post. Have an issue with my Sony tablet S. When I plug in my wired headset with screen off, it would not detect the wired headset, and music continues to play from speakers when I turn on the screen and play music. However, when I turn on my screen, plugs it in, it's okay. Same thing happens when I am unplugging the headset. Screen on, unplugging it will enable sound from speakers, but unplugging it when screen off somehow makes the tablet think that the headset is still connected. Am I having a defective set? Or software issue? Thanks Am running stock ics, 4.0.3 rev 1a. Thanks all.
