PulseAudio: Unable to connect: Connection refused

Hi everyone. I'm trying to get jasper set up on raspberry oi 3. I have most of the errors worked out but I'm still having some trouble with alsa. This is the message I get when I run jasper,py

Running both arecord -l and aplay -l both give me a (correct) list of devices. I reinstalled libasound2, but it had no effect. Any help would be appreciated!

My 1st question would be do you supply your RPi with the (actually) necessary 3A? The requirements on the RPi website for the RPi3 are completely inaccurate as most have found out. Usually the RPi will show a lightning bolt in the corner for any, and all power issues. Also 2.5A (as "required" according to the RPi website) will never give you remotely enough power, and other than flash memory (thumb/ finger sized usb drives) the RPi can not use anything VIA usb 2.0 without a powered usb hub. That means a hub with an optional power supply that converts AC to DC in order to power your devices correctly. However in the case of the RPi 3 it is mandatory to use the "optional" power supply the usb hub comes with, and the RPi3 can not be connected to this usb hub for it's own power because hubs do not give enough amperage to run the RPi.
