.After the certain moment, my speakers don't work, when the headphones get unplugged (3.5 mm jack). There is only speakers icon in playback tab, no matter, whether headphones are plugged in or not. Is there a way to determine, whether windows7 detects the headphone jack as plugged in, even if it's not? (that would be hardware problem then, I guess). If so, how to disable jack detection, so that the speakers can get unblocked? Or suggest any other solution. Thanks for replies.
