Can you please:

1. Reboot and then while audio is working run:

   pidof pulseaudio

2. Wait until audio is not working and then again run:

   pidof pulseaudio

3. Wait until audio starts working again and run:

   pidof pulseaudio

Do you get different results from those commands each time?

[Daniel van Vugt (vanvugt)]

Please also follow these instructions to check for crashes on the system:

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

[Daniel van Vugt (vanvugt)]

Finally, if the PID of pulseaudio is changing and there is no evidence of a crash then please try:

1. Edit /etc/pulse/daemon.conf and add a new line:

   realtime-scheduling = no

2. Save your changes and reboot.

[Filip Golab (sh333lby)]

Hey, thanks for helping me, I got a few updates regarding this issue:

- pidof is not changing

- I uploaded the crash report, but its not listed in my bug tracker(chromium crash)

- I found out that audio works perfectly fine when the laptop is plugged in or the battery % is above 20 - 40%

Let me know if you need more details.

[Filip Golab (sh333lby)]

I forgot to tell you: this issue is only pressent on ubuntu, audio on Windows works fine

[Daniel van Vugt (vanvugt)]

I wonder if 'tlp' or similar is at play...

Can you please run this command:

  dpkg -l > allpackages.txt

and then send us the resulting file 'allpackages.txt'?

[Filip Golab (sh333lby)]

There you go

[Filip Golab (sh333lby)]

Hello, it seems like now audio is not working even when on full battery or plugged in. It's so weird.

[Daniel van Vugt (vanvugt)]

Next, please wait until the audio has stopped working AND has later come back, then run:

  dmesg > dmesgafter.txt
  journalctl -b0 > journalafter.txt

and send us the files 'dmesgafter.txt' and 'journalafter.txt'.

[Daniel van Vugt (vanvugt)]

Also, does this bug apply to the laptop's internal speakers? Or are you using headphones?

[Kai-Heng Feng (kaihengfeng)]

Nothing wrong in the dmesg.

[Filip Golab (sh333lby)]

I was not able to replicate this bug for couple of days, thats why I have not uploaded files you requested. I'm not sure if it's gone, or is it just temporary. It used to affect both speakers and headphones. I will let you know when it's back

[Daniel van Vugt (vanvugt)]

No problem. If the issue doesn't return after 60 days and there are no further comments then this bug will automatically close.

[Filip Golab (sh333lby)]

I did return yesterday. I uploaded the files you requested before.

[Filip Golab (sh333lby)]

[Launchpad Janitor (janitor)]

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

[Daniel van Vugt (vanvugt)]

Please try live booting 19.04:

http://cdimages.ubuntu.com/daily-live/current/

and tell us if audio works there.

[Gabriele Ara (gabriararauna)]

Hey there, same problem here, audio has strange glitches, maybe we could reopen this issue? Both a collegue and I bought this same laptop and we are both affected by this issue, even on recent kernel builds.

[Gabriele Ara (gabriararauna)]

I can confirm that the same problem affects 19.04 too.

[Filip Golab (sh333lby)]

Hey, Im not quite sure how I can reopen it, if you could tell me I would do it for you. For me this issue had fixed randomly before I upgraded to 19.04 and was not pressent since then.

[Daniel van Vugt (vanvugt)]

Filip,

Since you are the original reporter and no longer experience a problem then I would prefer to keep this bug closed.

Gabriele,

If you are experiencing audio problems then please open a new bug by running:

  ubuntu-bug pulseaudio

so that we can review the details of your affected machine.

[Gabriele Ara (gabriararauna)]

Will do, thanks.
