Sound stopped working after update 11/06/18 7pm GMT

Status changed to 'Confirmed' because the bug affects multiple users.

Have the same problem with HP ProBook 430 G4.
Linux 4.4.0-127-generic – works

Linux 4.4.0-128-generic – fails with:
[ 33.066658] snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to polling mode: last cmd=0x208f8100

When trying to play something:

Sound also fails with Linux 4.4.0-130-generic.

Also tested several mainline builds from http://kernel.ubuntu.com/~kernel-ppa/mainline/:
v4.4.128 (4.4.0-127-generic) – sound works.
v4.4.134 (4.4.0-130-generic) – sound works.
v4.4.137 – sound works.

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 1776416

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.

Did this: 'apport-collect 1776416'. Then was asked you need to run 'sudo apt-get install python-apport' for apport-collect to work. Output attached to email: Re: [Bug 1776416] missing required logs 15/06/18 17:16. Sorry, I didn't how to post the output here as newbie.

A computer is 50% useless without sound. You don't seem to be in hurry
to roll this back to end my misery. This is the second time this has
happened, the first had to be fixed by an engineer. Seriously thinking
of using Windows, or seeing an engineer again because of your update.
The thing I miss about Windows is the ability to 'Go Back' to a previous
session. PC Specialist whom built my high-end machine warned me not to
use Linux...

Same here. I fix would be great. I haven't tried to boot with older headers though, maybe you'll get some sound back @surfsecret ?

Sound working again thanks to an engineer. Apparently, the sound drivers need to be updated. Would have hated to use Windows 10 as their updates are dreadful.

> Sound working again thanks to an engineer

Could you explain how was this fixed? Ain't the drivers supposed to update automatically with the system update?

I went off on holiday and hoped the bug got fixed in the meantime but apparently not. :(

Well, if the drivers were being updated automatically with a system
update they weren't for me.

The engineer didn't explain exactly what he did, sorry.

The repair wasn't expensive, so maybe you should get an engineer to look
at?
