RE: 7359 2-in-1: No sound from speakers after BIOs update
Had this same problem 6 months ago with a new laptop that got a bios update. The roll back was the ONLY thing that worked. 6 months later I had forgotten about this solution when the sound stopped working again and nothing else I tried worked. The clue that it was bios related was 1) my computer had just been auto updated by Dell and 2) a restart holding down the F4 or F5 keys would reactivate the speaker sound but not headphone jack. And if I restarted normally after this the sound was gone again! Finally remembered this page and the roll back solution. But when is Dell going to fix this ****?
