I am using DELL latitude E5530 non-Vpro computer, i installed both Ubuntu 19.04 and windows 10 19H1 in separate partitions. I have updated all the drivers including sound and microphone. but in Ubuntu I can use built-in Microphone to record voice or call on Skype and etc... But in windows it prompts that you don't have microphone. My computer has one place for headphone at right bottom of computer with Headphone ICON. I updated the driver hundreds of time. I installed a fresh copy of windows and updated the driver again but still i have the problem. Note! No external microphone works too.
