Bug Description

This seems to be a common problem on XMG Clevo W230SS there is no output on the headphone jack after suspend. The headphones are detected and the speakers are muted, but there is no output to the headphones. Init-headphones does not help:

sudo init-headphone
WARNING:root:Kernel parameter is missing: acpi_enforce_resources=lax
WARNING:root:Module is not loaded: i2c_dev
ERROR:root:Can't find i2c bus
ERROR:root:Operation failed

Any workaround beside reboot?

So, after a while tried it again and I finally managed to get the headphone jack working:

1) Update to grub2 if this has not yet been done.

2) Set the following acpi kernel parameter in /etc/default/grub

GRUB_CMDLINE_LINUX="uveau.modeset=0 acpi_enforce_resources=lax"

3) update-grub

4) Reboot

5) After suspending, run init-headphone to reactivate the headphones.

You can automate the headphone reactivation by adding the script /lib/systemd/system-sleep/init-headphone with content:

#!/bin/sh

if [ ! -x /usr/sbin/init-headphone ]; then
    exit 0
fi

case $1 in
     resume|thaw|post)
        /usr/sbin/init-headphone
        ;;
esac

This is similar to old workarounds found elsewhere on the web, but with xenial /lib/systemd/system-sleep/ has superseded by /etc/pm/sleep.d/ and the case "post" has to be added.

I can confirm this exact same problem still exists today. Is there any easy workaround for this?

Did you try the workaround posted on 2016-12-19? You may have to add modules i2c_dev and i2c_i801 before running init-headphone:
sudo modprobe --first-time i2c_dev
sudo modprobe --first-time i2c_i801
