I dual-boot with Ubuntu, and ever since I first installed it I was never able to hear any sound on the Ubuntu installation, but it worked great in Windows. Finally today out of sheer frustration I plugged my crappy ear-buds i use for my smartphone into the front panel of my computer and the sound works great in them! My only problem is I want the sound to come through my nicer headphones, which are plugged directly into the soundcard in the back. No sound ever comes out of them. The front panel is also connected to the soundcard, so I know its not a compatibility issue with that. Is there some setting I can't find? I assume all I have to do is just change something to select the output as backpanel instead of front, but I couldn't find it anywhere on Google. If anyone has any ideas it would be much appreciated!

EDIT: All the sound is turned all the way up for everything in ALSA Mixer and it still doesn't work :(

Here are the command outputs:

    Could you please edit your question to include the output of the terminal commands lspci -nnk | grep -A2 Audio, aplay -l, and pactl list short sinks? Please also make sure that the relevant audio channels in alsamixer (terminal) or gnome-alsamixer (GUI) have their volume turned up and aren’t muted. Thanks – David Foerster May 25 '17 at 17:17
  • For sound problems I recommend install of pavucontrol and then play with it – dargaud May 25 '17 at 19:23
  • I put in what you wanted for the edits. – Bioniclex6 May 25 '17 at 21:03
