Audio not working on FydeOS (Lantis)

I had installed FydeOS 17 on my HP chromebook 14a Lantis. And I cannot get audio to work, help would be appreciated

I don’t think FydeOS is supported. You are better off using brunch framework. If your Chromebook is not EOL you can use an official recovery image for your device on UEFI with the native_chromebook_image option. If your chromebook is EOL you can use a different, supported image witth the chromebook_audio option.
