I have an ASUS UX303UB laptop that I got for Christmas. The audio sounded awful (zero bass) when I first got it so I consulted the Internet and uninstalled the "Contextant SmartAudio HD" items in the device manager (maybe that wasn't a great idea) expecting to have to reinstall new ones but when I restarted the laptop It already had new drivers called "High Definition Audio Device". I looked this up and apparently it was normal and the audio sounded far better than before so I kept it and watched a few hours of shows. There was occasional stuttering/loud buzzing noises which scared me because my parents laptop had that and now it crashes constantly. I left for something and when I came back everything was frozen except for the cursor and the audio still played but Ctrl Alt Del didn't work so I shut it down and when I restarted it had reinstalled the Contextant drivers with the same abysmal sound. I have undergone this process several times since. Any advice?
