Hello, I have no sound in my laptop since yesterday. I checked everything according to the guidelines from the forum. Everything is as it should be. I suspect it's something inside. Can anyone in what it can be and what are the repair costs? The laptop is not new, it has been around for 5 years. Could this be related to the failure? There is no sound when testing the speakers. Everything is fine in the device manager, the icons are also as it should be.
