Hi all, Lately my laptop has no audio, says 'No Audio Output Device is installed'. So I go the device manager and find 'High Definition Audio Device' under sounds tab missing. I go under system devices and find no device that has an exclamation mark. I already updated my drivers but it's still missing. But here's the weird thing, every now and then the audio would work and when i check the device manager again, the high definition audio device is there and working,i tried updating it but it says its already updated. The next day it's gone again. I tried doing all kinds of things people suggested but it still wouldn't work.
