Home->Sound->Manage sound system->Output Devices This shows "Headphones" when phones are plugged in and it shows "Speaker" when phones are not plugged in. In both cases sound is provided by the speakers. I would have expected to hear sound in my headphone but not from the speakers. There is no sound coming out from the headphones. It appears the computer recognizes that the headphone connector senses the presence of the headphones but does not switch from speaker to headphones. I purchased the surface pro 6 only three weeks ago and can still return it, but I want to know if there is some hardware or software problem that could be corrected by me. As my time runs out, I would appreciate any early advise.
