I closed the lid of my laptop, when I opened it, there's no sound from speakers or headphones.

It also happens if I boot Windows and restart to boot Ubuntu. If I shutdown the computer and turn on then boot with Ubuntu and the sound works fine.

I've followed the instructions I could find on askubuntu, and Sound Troubleshooting Procedure yet nothing works. Please help. enter image description here enter image description here

Let me know if it works. The command below will load your snd-hda-intel module by appending it to /etc/modules, you might need to do a log off/log in. echo "snd-hda-intel" | sudo tee -a /etc/modules

  • Thanks, @root. That "kind of works". That makes the headphones work but not the speaker for both music on my computer and online (youtube, spotify...)

  • You forgot to put your system specs, but anyway, this document may be helpful. Follow the instruction to diagnose the problem and then append the options snd-hda-intel model=YOUR_MODEL to the /etc/modprobe.d/alsa-base.conf file. docs.slackware.com/howtos:hardware:audio_and_snd-hda-intel

  • I've updated the specs above. I've tried with model=ALC295 Analog but permission denied.

  • You need root access sudo vim /etc/modprobe.d/alsa-base.conf, then append the options line.

  • It worked, but then I restarted my computer and again there's no speaker sound.
