I observe this on my XPS 13 9360.
As mentioned by others, the headphone hissing goes away when I mute the system
or when I run "amixer -c0 sset 'Headphone Mic Boost' 10dB". I created an even
in /etc/acpi/events to call run this whenever headphones are inserted so that
it persists after
Indeed, I forgot to upgrade so I missed the issue. Now that I did I see
the hiss is indeed much louder. Thanks Kai for sending this upstream
already.

Like several of the most recent posters above I've had a 9360 for a
couple of years without any hiss problems. A few days ago I started
getting a pretty bad hiss thru headphones. Tried various headphones -
all have bad hiss. All are ok on other devices. Running 19.04. Something
has changed.

I've had this issue since 2017 all the time. As you can see in the
comments, Kai suggested that this is an hardware issue. He developed a
workaround for the kernel that I tested, however it made the general
output volume significantly lower, see #96, which is the reason this fix
was never shipped.
Same issue as previous 3 reporters. All was fine until the latest
update(s), I now have the hiss back... Any idea on what might've
changed?

The same happen with my XPS 13. Since a couple of days I have noticed
this annoying hiss. I use Ubuntu 19.04.
The workaround also fixes the issue for me (amixer -c 0 set 'Headphone
Mic Boost',0 1)

I've recently just run into the same problem since recent updates, I've
had my XPS since October 2017 and am currently running Ubuntu 18.04.3.
No issues until last week. I think I may have selected "headset with
microphone" by accident once when inserting headphones without a
microphone, but no
Weird. I've had an XPS 9360 running ubuntu since November 2017. Last
week I picked up all the updates from August, rebooted and ran straight
into this bug with headphones that had previously been fine. I dual boot
into Windows and that is fine so it isn't a hardware problem.
