LG Gram sound issues after rebooting Ubuntu

Bug #1763994 reported by Thomas on 2018-04-14
This bug affects 6 people
Affects Status Importance Assigned to Milestone

Bug Description

I tried Ubuntu 18.04 beta from a USB stick and encountered a few issues:

1. Shutdown seems to often (but not always) "hang", the console still accepts text I type but it doesn't want to actually complete it. Ctrl+Alt+Del "finishes" it.
2. After I booted Ubuntu, the laptop makes very loud and weird random noises, even as early as the BIOS/UEFI stage, before the bootloader. If I then boot into Windows 10, the crackling and static noises continue until I reboot the box again. This *only* happens the first boot into Windows after using Ubuntu. Sound in Ubuntu appears to work fine.

I don't know how to best describe the loud noises, so I recorded a short video: https://vimeo.com/264778133

Here's the output of lshw:

I can confirm the problem with loud beeping sound at bios booting time. In my case it can be interrupted by long-pressing power button until the laptop switches off, the next boot works well.

I came up with a fix and now it's in the queue for future stable kernels.

The next Canonical kernel should have the fix for this included.


ALSA: hda - Turn CX8200 into D3 as well upon reboot
ALSA: hda - Sleep for 10ms after entering D3 on Conexant codecs

Awesome! Thanks so much! I'll give it a try once 18.04 is on one of these kernels.

Unfortunately Bionic is still on 4.15.0, so I haven't been able to confirm the fix.

You can always install different kernel with UKUU - Ubuntu Kernel Update Utility

Hi guys!
My laptop is same model and there's the same issue. I use Ubuntu 18.04 and Kernel. I tried to install diff kernel like 4.17.18 and 4.18.4 but when I reset Ubuntu, I have a wrong and I have to change to last kernel that it's working...

Any suggestion ?

Thanks in advance

LG gram 15z980 with ubuntu 18.04 and 4.15.0-45, same issue! Really load and annoying...

@Salvador You maybe have a problem with secure boot that is not allowing unsigned kernels to boot. So 4.17.18 and 4.18.4 are not signed with certificate for secure boot.

@jiyuyan Try with 4.17.18 kernel, I'm using it and no problem. You can get the kernel with UKUU.

My question is, are these fixes going to end up in some official kernel we can use on Ubuntu 18.04?

Had same problem today. I had new LG Gram 15Z980.

Have been using for a couple of days only with W10 that came installed by default. Today I've installed Linux Mint 19.1 and just after installing from live USB, the first reboot started making strange noise.

As soon as I heard that I just power off and power on again. Randomnly after rebooting from Mint some strange sounds appears even before reaching booting screen, in the LG logo screen.
