Good day sir, I have a hp elitebook 840 g6 that as an audio fault issue: on window desktop, on the speaker icon it show a red cancel ❌️ sign that no audio output device plugged, however when I turn on the system the speaker make a sound of warning 'battery alert, also in 'bios setup' speaker works fine making a beep sound, but in Windows it is 'no audio output', I ave install an audio driver but problem not solve. What hardware fault could it be having? Could it also be a bios problem?
