Bug Description

Running the command alsamixer allows me to manually increase the sound levels for the headset, and sound plays properly through them. This requires me to disable the auto-mute feature.
I haven't rebooted my system yet to see if this is permanent.
But the UI doesn't show the heaphones at all and only sends sound through the main speakers of the laptop.

➜ ~ lspci -nnk | grep -i -A7 audio
00:1f.3 Audio device [0403]: Intel Corporation Device [8086:a348] (rev 10)
 Subsystem: Razer USA Ltd. Device [1a58:2001]

 Subsystem: Razer USA Ltd. Device [1a58:2001]

 Kernel modules: i2c_i801

➜ ~ cat /proc/asound/card0/codec* | grep Codec
Codec: Realtek ALC256
Codec: Intel Kabylake HDMI

Using for example pavucontrol allows me to select the headphone, which are marked as unplugged, and I can play audio through them as long as I keep the application open.
If I reboot or close pavucontrol, everything is back to the original state and only the speakers work.

Additional Information:

➜ ~ lsb_release -rd
Description: Ubuntu 18.04.1 LTS
Release: 18.04

What I expect to happen:

When I plug in my headphones, Ubuntu and the UI should see them and automatically redirect all sound through them.

I've taken a screenshot of the alsamixer.
This configuration currently is the only way for me to get sound out of my headset and not the speakers:

* Enable master sound
* Enable headphones, and assign volume
* Enable speakers, but put volume to 0, don't mute
* disable auto-mute

What laptop model do you use? Upstream kernel driver has regular fixes like https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/sound/pci/hda/patch_realtek.c?id=c1732ede5 (the one should be in the current kernel already though)
