Add two more ground connections.
Remove two I2C pull-up resistors.
Double check power connections and I2C connections to Pi.
I will do that tomorrow, but it surely won't hurt to have additional pull-up resistors will it?
No. Not all all. Electronic circuits like having extra components stuffed in, even if they're unnecessary. It makes everything more "electronicky". Put some valves in there too, for that authentic warm sound.
