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xenial /lib/systemd/system-sleep/ has superseded by /etc/pm/sleep.d/ and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.

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
