Add audio_output FIFO to mpd.conf

[Tim Curtis]

Have a look at /var/www/command/worker.php in the section headed by the comment line below. You will see that this block of code will enable only one of the outputs based on whats returned by configMpdOutputs().

// start mpd

If for some reason the fifo output is excluded internally by MPD from being disabled then you might be ok.
