It looks like you might have wired speakers to the grounds there - a very easy mistake. Even though I've made three now I still keep the pinout handy. Try these highlighted points
Also: I was unaware that the ethernet had 3.7V so easy accessable! That would have saved me some creative wiring had I thought of it!
yes, I made a mistake with the wires, but that's not all, I also found out that the audio controller does not have 5 volts, which means that it burned out?
