I recently got an Asus Vivobook. It worked perfectly on Windows but since I moved on Ubuntu (20.04 and 22.04), I don't have any sound from the speakers.

My sound device is : HDA Intel PCH, ALC294

I tried to:

  1. reinstall Ubuntu 20.04 and then install Ubuntu 22.04
  2. edit the /etc/modprobe.d/alsa-base.conf file as suggested here: https://doc.ubuntu-fr.org/audio_intel_hda

None of the above worked.

lspci -v command returns this:

0000:00:1f.3 Audio device: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev 20) (prog-if 80)
    Subsystem: ASUSTeK Computer Inc. Tiger Lake-LP Smart Sound Technology Audio Controller
    Flags: bus master, fast devsel, latency 32, IRQ 185, IOMMU group 14
    Memory at 612f288000 (64-bit, non-prefetchable) [size=16K]
    Memory at 612f000000 (64-bit, non-prefetchable) [size=1M]
    Capabilities: <access denied>
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel, snd_sof_pci_intel_tgl

PS: I have this error at startup that could be a way, but I have no idea of what it is:

error at startup

I am very new to Ubuntu, so I'm sorry if it's a basic question, but I haven't found any solution until now.

Thank you all for your help!

  • I had the same problem with a Asus Zenbook UX463F since the 22.04 upgrade and this worked for me : linux.org/threads/…

Reset to default

Add loglevel=3 to GRUB_CMDLINE_LINUX_DEFAULT in etc/default/grub, so that it will look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=3"

Then update GRUB using this command:

sudo update-grub

That's it.

Note that the above didnt't fix the ACPI BIOS Error, but now my speakers are working perfectly.
