Recently I installed El Capitan (in a clean installation because a troubles after install) and I can't enable the audio. In my first installation (update from Yosemite) all was well but a few days, when I reboot, the logo freezes and that's all. In that installation the audio works fine (only the backside ports) BUT in this installation (the clean installation) I can't fix the audio.
I tried a many tutorials for fix it but nothing result; also I followed a tutorial for a recognized dev but still not working. I leave my console output and specs of my computer. Please help and enjoy your weekend.
