I purchased an Acer SP513-53N and used it for gaming, animation, rendering, and school. However yesterday, my device ended up going on a complete freeze. I couldn't do anything at all so I decided to shut down the laptop by holding the off button. After turning it back on, my device couldn't detect any audio input and output devices (Including the Internal speakers). I have tried to reset the laptop twice, but after checking my device manager: the audio driver for the internal speakers has disappeared. I don't know what to do now.
