Hi I currently can't hear anything on my netbook, I'm running lubuntu 18.04. when I open alsamixer it says: imagen de alsamixer

as you can see it recognize my sound card which is Realtek ALC259 but it uses HDA Intel as a driver so I can't hear anything, any ideas how to fix it?

  • master volume level is 00 ? – cmak.fr Jun 16 '18 at 23:08
  • put it at 100 still no sound – Danilo Jose Jaimes Hidalgo Jun 16 '18 at 23:15
  • if pulseaudio is not installed, try installig pulse audio first. It has way easier handling than alsamixer. If you are missing sound in VLC or any other program where you can select which soundcard to use than select the soundcard to use within that software. If you want firefox to be using the soundcard, things become difficult, because you need to change the default soundcard to the one you want to use. There are workarounds to achieve this, but none is perfect. https://askubuntu.com/questions/167394/sound-card-selection and http://www.alsa-project.org/main/index.php/Asoundrc – AlexOnLinux Jun 17 '18 at 02:27

the short answer is run this command in terminal and see if you now can hear : 

sudo modprobe snd-hda-intel

and if it worked for you, you need to run it whenever you login into the system : 

sudo sh -c 'echo "snd-hda-intel" >> /etc/modules'

and for more info about sound's problems you can checkout my answer here : Headphones not detected when plugged before boot

UPDATE when you opened your alsamixer please press "s" and select your sound card then it will work probably
