I hope I can get some help here as I couldn't find any solution for Intel on google

If there is some other commands which could help please type them, I'm really new and don't know much yet.

  • Did you check if you could get any sound from the sound adapter directly (speaker or headphone)? Did you try simply playing a basic music file like a mp3? – Julie Pelletier Aug 11 '16 at 17:40
  • It works on laptop build-in speakers and when I plug-in headphones, but still won't work on HDMI, nor mp3 nor Firefox – Atteru Aug 11 '16 at 17:50
  • There is a little update after a month: I have it fixed somehow, don't really know how, but now there is a problem with docking station, I cannot get audio working over HDMI output of Docking Station, have somebody seen this issue? – Atteru Sep 27 '16 at 5:34
  • These issues could be as simple as a bad connection. – Julie Pelletier Sep 27 '16 at 5:49
  • What do you mean by bad connection? There is only problem with sound over HDMI from docking station, everything else, like audio jack, USB ports, and video over HDMI is working perfectly fine. – Atteru Sep 28 '16 at 11:40
