Hello,

I recently bought an Asus Zenbook 14 OLED (UX3402ZA) and the speakers are not working at all on any Linux distribution. I've tried openSUSE, Ubuntu (I'm currently running it), Fedora KDE but no dice.

Here's some info about my system:
uname -a:
Code:
Linux zenbook 5.15.0-41-generic #44-Ubuntu SMP Wed Jun 22 14:20:53 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

aplay -a:
Code:
card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: sofhdadsp [sof-hda-dsp], device 1: HDA Digital (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: sofhdadsp [sof-hda-dsp], device 3: HDMI1 (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: sofhdadsp [sof-hda-dsp], device 4: HDMI2 (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: sofhdadsp [sof-hda-dsp], device 5: HDMI3 (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Inxi -a:
Code:
Audio:
  Device-1: Intel Alder Lake PCH-P High Definition Audio
    driver: sof-audio-pci-intel-tgl
  Sound Server-1: ALSA v: k5.15.0-41-generic running: yes
  Sound Server-2: PulseAudio v: 15.99.1 running: yes
  Sound Server-3: PipeWire v: 0.3.48 running: yes

I also tried the solutions discussed in this thread: https://www.linux.org/threads/solve...altek-hd-audio-problem.27384/#google_vignette
Still no luck.

That said, I've seen many more threads on various forums from users which have a similar or the same laptop as me, reporting that their audio is also not working. Some examples:

I desperately need help fixing the audio. The laptop shipped with Windows 11 and the speakers worked perfectly, until I decided to install Linux. I really don't wanna go back to Windows but if this can't be fixed I'll have to :(...

Hello,

same issue - almost same device (UM3402YA - 5.18.15-arch1-2). I want to share the information I have gathered.

Possible cause
I hope I'm on the right track...
If I understand this thread correctly the sound system on this device is composed of multiple sound cards (CS35L41) and a connector node (CSC3551) - https://superuser.com/questions/1719920/.
The connector node (CSC3551), which is connected to the CPU via the i2c-bus, doesn't seem to be supported yet.

Possible patch?
There was communication between the kernel devs and somebody working for Cirrus (the manufacturer of the sound system) about supporting this sound configuration - https://patchwork.kernel.org/[email protected]/.
Where the kernel devs concluded:
As the ic2-multi-instantiate patch chain is still being worked out, we would like to submit a new chain for CLSA0100 id and a few fixes for the HDA cs35l41 driver. And to avoid conflicts the ic2-multi-instantiate patch chain will wait for this new patch chain to be merged.
Ok, so the CSC3551 has to wait for patches of the CS35L41?

I don't have the knowledge to apply any of the changes made to the kernel. I don't want to go back to Windows neither so I guess we just have to wait for the kernel patch except someone comes up with a fix.
