I'm new to linux world, I've installed Mint 18 with Cinnamon desktop, but I have a problem with audio over HDMI neither on my monitor or TV here is kernel, and list of audio devices:

 ~ $ uname -r
4.6.0-040600-generic
 ~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 0: ALC3235 Analog [ALC3235 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

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?

  • It works on laptop build-in speakers and when I plug-in headphones, but still won't work on HDMI, nor mp3 nor Firefox

  • 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?

  • These issues could be as simple as a bad connection.
