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?

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

Daniel van Vugt (vanvugt) wrote :

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) wrote :

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) wrote :

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

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'?

There you go

Filip Golab (sh333lby) wrote :

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) wrote :

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'.

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

Nothing wrong in the dmesg.

Filip Golab (sh333lby) wrote :

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

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) wrote :

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

Please try live booting 19.04:

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) wrote :

I can confirm that the same problem affects 19.04 too.

Filip Golab (sh333lby) wrote :

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) wrote :

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:
