Hello all. I'm helping a friend of mine with their Dell Inspiron laptop. It's a 15" P58F and it has no sound output from the speakers or the headphone jack. Device manager shows that the audio device (Realtek Audio) is working fine. I uninstalled the driver and installed it again, updated driver and installed latest windows updates. Still not working. The only way we get sound is with a bluetooth device. Other than that, I booted into the diagnostic F12 mode and did an audio test. I did hear the chimes through the audio test, so I know the actual speakers are working. Did I miss something?
