hi

I have tried a lot to find a solution to the problem of sound in my computer
I found some solutions in forum, but I do not know What I do I'm confused , I can not hear any sound
first thing i do , go to
configure your desktop - multimedia - phonon
i put [ Microsoft life chat lx-3000 ] the first one , then apply

after that i run audio by vlc and youtube .. there is no sound
i think maybe i need to restart my PC but also there is no sound
somebody told me to install PAVUCONTROL from synaptic
i installed it , There are several options
I do not know what I'm doing here and how to adjust the sound settings
