So, the problem I have is with the sounds. First, when I listen to music on Youtube it sounded distorted (like a broken vinyl plate), but when I was listening to a downloaded Audio file, it was fine. Then, downloaded files also got distorted and no sound at all was playing from Youtube.
And now - both Youtube files and downloaded files are dead, just some distorted sounds in the speakers (like smeshing metals) LOL!
I checked my sound settings, the test "left front" / "right front" works fine On terminal I got my soundcard listed.
And that's all I could do by myself. Please, help!
