Problem on disabled headphone jack after upgrading from Win 10 vers 1607

[Windows Central Question]

I bought Lumia 640xl and I upgraded it from Windows 8.1 to Windows 10 version 1157 to Windows 10 version 1607. Also my Lumia 550 which is Windows 10 version 1157 and upgraded to Windows 10 version 1607. There was no problem encountered during the upgrade, but when I insert the headphone, I don't hear anything, when I take off the headphone, there was sound. Bluetooth headphone works fine. Same with my Lumia 550. Any help
