Airplay won't enable

When I try toggle the Airplay feature on, I get this error:

Have tried following suggestions in related discussions here (eg #447) but my conf file looks fine.

How can I fix this?

Try:
[[ -e /boot/kernel.img ]] && sed -i '/ExecStart=/ d' /etc/systemd/system/shairport-sync.service.d/override.conf

That seems to have done the trick, thanks!

Out of interest, what was the problem and why did that help?

Cheers
