Headphones work only when unplugged and plugged in again
0
I have a Dell XPS 15 9570 with Ubuntu 18.04.
When I plug in my headphones I can listen to audio. Everything works fine.
Except from the shrill noise I get when I don't play any audio.
Another issue is that, if I leave the headphones plugged in and reboot the laptop, it appears that the headphones don't work, i.e. I cannot listen to any audio.
To be able to hear anything I have to unplug and plug in the headphones again.
How to fix these issues?
UPDATE
When I run journalctl --follow and plug in the headphones I get:

I then leave the headphones in and reboot.
After I run journalctl -b I get:

I have a Dell XPS 15 9570 with Ubuntu 18.04.
When I plug in my headphones I can listen to audio. Everything works fine.
Except from the shrill noise I get when I don't play any audio.
Another issue is that, if I leave the headphones plugged in and reboot the laptop, it appears that the headphones don't work, i.e. I cannot listen to any audio.
To be able to hear anything I have to unplug and plug in the headphones again.
How to fix these issues?
UPDATE
When I run journalctl --follow and plug in the headphones I get:
Oct 14 18:31:24 xps systemd[1444]: Starting GNOME Terminal Server...

I then leave the headphones in and reboot.
After I run journalctl -b I get:

Watch the logs as you plug in the headphones, withjournalctl --follow. See what your system did at boot, `journalctl -b

@waltinator I have updated the description of the issue. Can't tell if that reveals anything.

1. Unplug. 2.journalctl --follow. 3. Plug. 4. Check for "shrill noise"? 5.sudo lsof +D /dev | tee devices.open.txt.

I have a Dell XPS 15 9570 with Ubuntu 18.04.
When I plug in my headphones I can listen to audio. Everything works fine.
Except from the shrill noise I get when I don't play any audio.
Another issue is that, if I leave the headphones plugged in and reboot the laptop, it appears that the headphones don't work, i.e. I cannot listen to any audio.
To be able to hear anything I have to unplug and plug in the headphones again.
How to fix these issues?
UPDATE
When I run journalctl --follow and plug in the headphones I get:
Oct 14 18:31:24 xps systemd[1444]: Starting GNOME Terminal Server...

I then leave the headphones in and reboot.
After I run journalctl -b I get:

18.04 sound dell headphones
asked Oct 12 '18 at 23:11
Sandu UrsuSandu Ursu

I have a Dell XPS 15 9570 with Ubuntu 18.04.
When I plug in my headphones I can listen to audio. Everything works fine.
Except from the shrill noise I get when I don't play any audio.
Another issue is that, if I leave the headphones plugged in and reboot the laptop, it appears that the headphones don't work, i.e. I cannot listen to any audio.
To be able to hear anything I have to unplug and plug in the headphones again.
How to fix these issues?
UPDATE
When I run journalctl --follow and plug in the headphones I get:
Oct 14 18:31:24 xps systemd[1444]: Starting GNOME Terminal Server...

I then leave the headphones in and reboot.
After I run journalctl -b I get:

Watch the logs as you plug in the headphones, withjournalctl --follow. See what your system did at boot, `journalctl -b

I have identified the source of the shrill/hissing noise: it appears after running:
sudo apt-get install tlp tlp-rdw powertop
sudo tlp start
Removed it. Solved this issue.
I still need to unplug and plug the headphones back in every time I restart the laptop though.
