I am pretty new to the linux and dual booting so I will accept any new information.
Yesterday I dual-booted my windows laptop Asus-UX433FA, and I started with installing Ubuntu 18.04. I am having some problems but main one is Audio one. I cant play any sound neither on speakers or headphones. I tried with reinstalling alsomixer and pulsefire(as i remember) but that did not help. Today I tried upgrading to 19.04 because I read somewhere that new version solves my problem. Update obviously didn’t help, and neither did same methods as above.
When I play video on youtube I hear some noises like scratching for 2 seconds and then everything muted.
