My laptop is Dell Inspiron 15R - 7520 (Mid 2010)
After upgrading to Windows 10 and do a clean install after that, I let my laptop update all drivers from Windows Update. Then I go to Dell support page to download any missing driver. Finally, there is no unregconized driver in Device Manager.
However, "Hey Cortana" feature is not working with the microphone. (I have turned on Hey Cortana in Cortana Settings). The microphone still works well with Skype. It also works well if I click the microphone icon next to "Ask me anything" in Cortana textbox.
Anyone knows how to make "Hey Cortana" works? Is it because of the Conexant driver is Windows 8.1 version, not Windows 10?
