Internal speaker (Audio) is not working in Ubuntu 20.04

Question

Internal speaker (Audio) is not working in Ubuntu 20.04. Only Dummy output in the selection of output device.

UPDATE (2021-12-04) - I made a conclusion after reading posts of owners of Huawei Matebook D16 that the problem is with sound card (Everest) in this model of laptop. It's not supported yet.

Detailed alsa information: http://alsa-project.org/db/?f=0728a726fdfae280fcc1b9fc801432288a931cf3

**** List of PLAYBACK Hardware Devices ****
card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Generic [HD-Audio Generic], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Generic [HD-Audio Generic], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

There are only HDMI in the list of Playback hardware devices, may be problem is here? Notebook is Huawei Matebood 16D with AMD core.

I tried a lot of solutions found on the internet:

Add lines to "/etc/modprobe.d/alsa-base.conf"

options snd-hda-intel model=auto
options snd-hda-intel dmic_detect=0

Add "radeon.audio=1" to "/etc/default/grub"

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

Remove and reinstall "analog"

sudo apt-get remove analog
sudo apt-get install analog

Update linux Kernel to 5.15.6

Nothing helped to hear sound on Ubuntu :( Audio works on Windows.

There are only HDMI in the list of Playback hardware devices, may be problem is here? Yes. Internal speakers are connected to the internal sound card that isn't being detected. HDMI audio comes from the sound chip/layer in the GPU. — ChanganAuto, Dec 04 '21 at 12:21
thank you for answer. Is it possible to detect card ? i found https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS but there are no package for ubuntu 20.04 on amd64.. — Fedortaf, Dec 04 '21 at 12:26
Comments aren't answers. The intent was to confirm your suspicion and focus the troubleshooting. I don't know enough to help you with this but others hopefully can. — ChanganAuto, Dec 04 '21 at 12:29
I have similar problem with Ubuntu 22.04 kernel 6.5. Have you succeeded to fix it? — Jacek Blocki, Feb 07 '24 at 22:22

Your ALSA have loaded snd_acp3x_rn module, but card was not recognized fully, unlike snd_hda_intel. Since you are using dual boot, the problem can be ‘Fast Startup’, that puts hardware into a hybrid hibernation state instead of a full shutdown. Disabling Fast Startup is a must when dual-booting. Shutdown.

The origin of this hint is here: https://forum.manjaro.org/t/sound-from-speakers-no-sound-from-3-5mm-jack-audio-amd-thinkpad-e595/13717/6

EDIT: another idea. There can be wrong module loaded for your sound card. Try to blacklist the following modules in /etc/modprobe.d/blacklist.conf:

    blacklist snd_acp3x_rn
    blacklist snd-acp3x-pdm-dma
    blacklist snd-acpx-rn
    blacklist snd-rn-pci-acp3x

Blacklist them one-by-one, reboot after each. Check the result with aplay -l.

Thank you for answer. I disabled Fast Boot in Windows. There is not FastBoot settings in bios in huawei matebook d16. It disn't help. Apperently, it's a problem of new sound card in this laptop. – Fedortaf Dec 04 '21 at 15:13
@Fedortaf if it is Everest card, then, accordingly to this post it is not supported yet by current kernel of Ubuntu 20.04. – Alexander Grytsenko Dec 04 '21 at 18:51
