When I startup my laptop audio is working, when i put my laptop in sleep and then start using it again audio is not working. I can edit the volume, it sees when a headphone is plugged in. But it won't give any sound via headphone and internal speakers. I'm using layout 28 on my Asus K53SV-SX704D with ALC 269VB sound chip. Do you know what the problem is? And could you fix it?
