How Do You Get Audio to Work on Your Linux System?

Problem scenario
There is no audio on your Linux system. The volume is not muted. In the control panel area for audio you see "Dummy …" for your sound device on your Linux system. What should you do?

Possible Solution
This assumes the hardware of the server, computer or laptop uses Intel.

  1. Backup the file /etc/default/grub (e.g., to your home directory as .bak).
  2. Modify /etc/default/grub. Find the stanza for "GRUB_CMDLINE_LINUX_DEFAULT" and append a space to it and this stanza:


It will look like this (but "quiet splash" may be something else):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd-intel-dspcfg.dsp_driver=1"

  1. Run this command:
    sudo grub2-mkconfig -o /boot/grub2/grub.cfg
  2. Reboot the server.
