On my mothers laptop the sound has suddenly disappeared. Ive checked the volume settings and nothing is muted and the volume bars are at maximum. Ive checked the hardware manager and all of the audio hardware is enabled and it says that they are working properly. The output of the sound in the properties is also set to the only audio output. Ive also tried to plug my headphones in to the laptop to make sure that there isnt anything wrong with the speakers but i couldnt hear anything.
What might be wrong with the laptop or its settings?
