The sound device of my laptop always disappears while I am using it, then it comes back after I restart the computer. After that, it keeps disappearing every 30 min of usage.
Please, help me out, I thank you in advance.
Try to use the Services menu to configure the sound service to restart automatically. This symptom was previously encountered in case of a virus infection. At some point there was a virus, which primarily targeted the sound drivers. Go to Start > Run and type in services.msc. Locate Windows Sound and right click it. Select Recovery and use Restart the service on first and second failure.
