I'm very new to Linux environment. I have installed parrot security on my Acer Aspire E5 573G. I'm not much aware about using "linux as my daily driver" so when I try to run any multimedia file they don't run. I have vlc pre-installed but it won't open. When I try to watch videos on youtube there's no sound. Am I missing some drivers or something? I think all the necessary drivers are installed during the OS installation right? Any Ideas?
