I have been trying for the last weeks to get the sound working on my Huawei Matebook D laptop.

System:    Host: iason-NBLB-WAX9N Kernel: 5.13.0-28-generic x86_64 bits: 64 compiler: N/A 
           Desktop: Gnome Distro: Ubuntu 20.04.3 LTS (Focal Fossa) 
Machine:   Type: Laptop System: HUAWEI product: NBLB-WAX9N v: M1010 
           serial: <superuser/root required> 
           Mobo: HUAWEI model: NBLB-WAX9N-PCB-B2 v: M1010 serial: <superuser/root required> 
           UEFI: HUAWEI v: 1.34 date: 06/07/2021 
Audio:     Device-1: Intel vendor: QUANTA driver: snd_hda_intel v: kernel bus ID: 00:1f.3 
           Sound Server: ALSA v: k5.13.0-28-generic

The following is the actual PCI device:

00:1f.3 Multimedia audio controller: Intel Corporation Device 02c8

I have tried reloading ALSA, updating drivers etc. but none of these work. Currently, when I go to settings a generic input/output device is listed but it does not work. Any suggestions? I cannot use sound through the PCI device, only through bluetooth devices.

The /etc/default/grub file may need to be modified for this to work. Fortunately, it's not too difficult to do:

  1. Open Terminal (if it's not already open)

  2. Edit the grub file with sudo and your favourite text editor:

    sudo {editor of choice} /etc/default/grub

    Note: Be sure to replace {editor of choice} with your editor of choice.

  3. Find the line that starts GRUB_CMDLINE_LINUX_DEFAULT and add this to the end, within the quotes:

    snd_hda_intel.dmic_detect=0

    After the edit, you may see something like this:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"

  4. Save the file and exit the text editor

  5. Update Grub:

    sudo update-grub

  6. Reboot

Your system should now properly detect and use the Intel audio device.
