Product: HP ProBook 450 G4 Notebook PC
Operating System: Microsoft Windows 10 (64-bit)

My audio(conexant speaker) isnt working on my HP laptop. I tried troubleshooting, uninstalling the drivers ,updating but there are no availabale updates. Errors i came across were (Device INTELAUDIO\FUNC_01&VEN_14F1&DEV_2008&SUBSYS_103C8231&REV_1001\4&792b185&0&0001 was not migrated due to partial or ambiguous match) on Windows event viewer and (Device install requested) on driver events. The audio works fine when i press F2 using HP bult-in troubleshoot but as soon as i restart the audio doesnt work. MY device is HP Probook 450 G4 Windows 10 Pro. I would really appreciate the help.
