Can you please explain in more detail what problem you are experiencing?

Headphones? Speakers? Microphone?

What works and what doesn't work?

[Erkan ÜNLÜTÜRK (erkan-unluturk)]

None of them sound, analog output looks(intel hdmi/dp lpe audio).. Including 18.04.2

alsa corrected in new version, here https://www.alsa-project.org/main/index.php/Changes_v1.1.7_v1.1.8

[Daniel van Vugt (vanvugt)]

I vaguely recall sound didn't work on Cherry Trail systems like this until recently. Could you please try live booting some newer versions of Ubuntu and tell us which versions have working sound?

18.04: http://releases.ubuntu.com/18.04/
18.10: http://releases.ubuntu.com/18.10/
19.04: http://cdimages.ubuntu.com/daily-live/current/

[Erkan ÜNLÜTÜRK (erkan-unluturk)]

Works in 18.10

[Daniel van Vugt (vanvugt)]

Thanks. That makes this bug Fix Released (because it is fixed in some release, any release). And I think the fix would have been in the kernel.

If you could try some different kernel versions, you might/should be able to find the version where it started working:

  https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D

Presently it seems that 4.15 is not working. But kernel 4.18 (in Ubuntu 18.10) does work.

[Kai-Heng Feng (kaihengfeng)]

Please find the first good -rc kernel [1] between v4.16-rc1 to v4.18-rc8.

[1] http://kernel.ubuntu.com/~kernel-ppa/mainline/

[Erkan ÜNLÜTÜRK (erkan-unluturk)]

Why doesn't work in 18.04.2 (kernel 4.18)

[Daniel van Vugt (vanvugt)]

Reopened due to bionic bug 1853439

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1816429

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Daniel van Vugt (vanvugt)]

Actually that still counts as Fix Released for 18.10, but incomplete for 18.04. Please answer comment #7.

i don't think it is kernel related, I also don't know how to do it, sorry.

[Daniel van Vugt (vanvugt)]

Since you said Ubuntu 18.04 is broken and 18.10 works then we need to identify which kernel version fixed the problem. Per comment #7 we believe this is probably in the range v4.16-rc1 to v4.18-rc8.

I suggest starting around v4.17. Please download:

https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17/linux-headers-4.17.0-041700_4.17.0-041700.201806041953_all.deb
https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17/linux-headers-4.17.0-041700-generic_4.17.0-041700.201806041953_amd64.deb
https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17/linux-image-unsigned-4.17.0-041700-generic_4.17.0-041700.201806041953_amd64.deb
https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17/linux-modules-4.17.0-041700-generic_4.17.0-041700.201806041953_amd64.deb

and then install them:

  sudo dpkg -i *.deb

and reboot.

Now verify the new kernel version is active:

  uname -a

and tell us if that has fixed the bug for Ubuntu 18.04.

[Daniel van Vugt (vanvugt)]

Oh, your latest apport upload was 18.04.3 already.

[Daniel van Vugt (vanvugt)]

Just to confirm where the bug is fixed, please also boot Ubuntu 19.10 and verify the bug is fixed there:

https://ubuntu.com/download/desktop/thank-you?version=19.10&architecture=amd64

[Daniel van Vugt (vanvugt)]

Also your latest upload from comment #12 shows:

!!Sound Servers on this system
!!----------------------------

Pulseaudio:
      Installed - Yes (/usr/bin/pulseaudio)
      Running - No

So we need to find out why pulseaudio is not running. Please check /var/crash for crash files. If there are any crash files then please follow these instructions:

https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

Otherwise please try editing /etc/pulse/daemon.conf and add a new line:

 realtime-scheduling = no

then reboot.

[Daniel van Vugt (vanvugt)]

To clarify why there's so much confusion here, it appears this started out as a kernel bug in older Ubuntu releases but is now a PulseAudio bug. Two separate issues.

[Erkan ÜNLÜTÜRK (erkan-unluturk)]

"realtime-scheduling = no" no change

[Erkan ÜNLÜTÜRK (erkan-unluturk)]

there is sound after 18.10 (19.04, 19.10)

[Erkan ÜNLÜTÜRK (erkan-unluturk)]

it makes sense to wait for the next LTS version

[Daniel van Vugt (vanvugt)]

OK then. We can say the bug was fixed in some Ubuntu versions but this might turn out to be one of those bugs where we don't know exactly where so can't backport the fix to older releases.

[Fábio Trentino Souza (fabiotrentino)]

In KDE Neon 5.17.5 this bug exist as well...
