Ok, I fixed my problem.
My firefly (v. 1696) is running on ubuntu and it turns out that the problem was that my firefly script /etc/init.d/mt-daapd wasn’t running as root and that was causing the problem.
*UPDATE*
I think I’ve finally fixed this by adding the line
/etc/init.d/mt-daapd restart
to
/etc/rc.local
Maybe this is a bad thing, or there is a simpler way, if so I’d like to know!
Cheers,
Lou
