I just got a new Chuwi Gemibook Pro and installed Linux Ubuntu 21.04 on it, and there is no sound. In “Output device” I see only Dummpy output, and after adding options snd-hda-intel model=generic in /etc/modprobe.d/alsa-base.conf it changed to “HDMI / Display Port - Built-in Audio” but it still doesn’t work. I tried different kernels (5.10, 5.11, 5.13) - all the same. Unfortunately I removed Windows before checking the sound so I don’t know is it a hardware problem or not.

Here is some information, please ask if you need more:

  • There is a thread in the MX Linux Forum. Most likely, it is not a hardware fault as it affects multiple people in multiple distros. Commented Sep 3, 2021 at 5:54
  • I have the same problem with Zorin OS 16, I tried some solutions that I found on the internet but still have no audio. It looks like you have made much more research to solve the problem. My solution is to use Bluetooth headphones and they works fine. Commented Sep 5, 2021 at 15:43
  • Bluetooth headphones is an option, but my microphone isn't working as well, and it's hard to make the microphone from the headphones work along with them. I want to try USB garniture

1 Answer 1


It is not hardware, as I am having the exact same issue on a Gemibook Pro, although on another distro, and there is a open bug on sof project. Even though that bug is initially for the Hi10X tablet, it is directly applicable to the gemibook pro, as it apparently has the same sound hardware, the ES8336 codec - [BUG] No local devices (speakers/headphones) on N4120 tablet (Chuwi Hi10X) #2955; there is a pull request linked at the end of the bug which indicates that support will come as soon as a driver is cleaned and pushed upstream. You can probably try it out by following the instructions for setting up a ktest environment and the pull request itself.

  • Thank you, I hope their fix will help, applying it by myself seems too hard. I wonder, do you have sound problems with Windows or it's just Linux?

  • It would be great if someone who knows how to compile this patch posts a step by step solution. Commented Sep 7, 2021 at 13:07
  • In windows sound works without issues. As for working code and documentation, they are in the sof github - the pull request has the code (github.com/thesofproject/linux/pull/2962) and the github wiki has the documentation, in this case the relevant one is the setting up the ktest environment - thesofproject.github.io/latest/getting_started/setup/…. I can copy it here but it would be redundant and subject to drift from the source.
