I've choose elementary OS for my first serious linux operating system, so please be lenient. I used to linux occasionally before and I hadn't any problems with drivers(?)
I searched a lot before I wrote this post, but any solution doesn't work for me :(
I have Asus laptop (model R510LC, "sonicmaster") with realtek chip. I've tried install drivers from realtek website, but in terminal "make" failed every time...
Internal speakers is unavailable in pavcontrol and doesn't work at all. Headphones works fine.
I've checked alsamixer too trying unmute everything, but it is still silence.
