Ok, that looks like the right power supply; it should be a PW1060, and you do have two as you should for six zones.
I have a couple of times in the past seen the streaming sources fail to work properly when connected to underpowered power-distribution modules.
You could as a test disconnect all your zones and try to bind it, and if that doesn’t work, while leaving the zones disconnected, swap the power supplies on the AU1002; it’s highly unlikely you’d have two going bad.
That’s the only other thing I can think of to rule out before determining you have either a bad 1002 or 7002.
