I am not sure you are on the right track with that link you posted as they talk about configuring mdp to work with pulseaudio.
I think what you are actually seeing is the mdp server timing out after 60 sec which a saw on another project I advised on.
in that case we edited mdp.conf to change the time out to 21 days.
If you want to try that this is how you do it.
so we are going to edit the mpd.conf file to do this use the following
this should open the mpd.conf file
now using the down arrow key move right to the end of the file just keep your finger on the down arrow key till it gets to the end its a long way there are about 400 lines in the file
when you get to the end of the file move to the end of the line of #'s using right arrow key and hit Enter.
you should now be on a new line.
now you need to enter the following
now mpd.conf is a bit fussy about spacing so after you have typed the connection_timeout bit hit the tab key then type "2000000"
now press Ctrl and O it will as the file name to write to just hit Enter it should say wrote 419 lines or there about dont worry to much about the number.
now press Ctrl and X to exit nano.
you should now have set the connection time out to about 21 days.
let me know if it solves your problem.
