Sound stopped working after upgrading to Linux 5.4 (Intel HD Audio)
Here is how I was able to resolve this:
sudo vim /etc/default/grub
- Find
GRUB_CMDLINE_LINUX_DEFAULT
and addsnd_hda_intel.dmic_detect=0
to the end of it. (ex:GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 snd_hda_intel.dmic_detect=0"
) sudo grub-mkconfig -o /boot/grub/grub.cfg
- Reboot the system.
The option snd_hda_intel.dmic_detect=0
is deprecated on newer kernels, you may use snd-intel-dspcfg.dsp_driver=1
instead.
But be aware, it's slightly different meaning.
