TTSGPIO not working! Can't find deamon

Hi everyone,
I am new to mopidy and I am trying to make a speaker with buttons to play and pause. I have installed pi musicbox succesfully and loaded ttsgpio with “pip”. The first time I launched, I had an error: ttsgpio/debug_gpio_simulate invalid value for boolean so I simply deleted the line in the config file. Now, they are no error messages but it still deosn’t work. I can’t find where to change deamon user from mopidy to root. Any help would be appreciated!

Please! I can’t figure this out.
