I'm hooking up Helders new AIO board which is super fun, however I'm not sure how to hook up the audio. I've attached an image how I currently connected it, but I'm getting no audio.
Does anyone know how it should be connected?
Sorry for the noob question, I'm quite new to all this.

Did you configure your raspi for PWM audio and wire up the appropriate gpio port for it? PWM0/1 pads on the AIO should go to GPIO 18 and 13 on the raspberry pi, see
http://Pinout.xyz and
http://www.sudomod.com/forum/viewtopic. ... 261#p12261 (light grey and brown wires in the first image).
Also see section 2 of
http://www.sudomod.com/forum/viewtopic.php?f=5&t=1185 for how to configure PWM audio in the startup files of the raspberry pi and some other tips.

I did hook up the pwm tothe raspberry pi correctly, however I haven't edited the script yet. So maybe I should do that first. Are my yellow wires wired correctly though?

Your speaker wire up looks ok to me. I don't believe speaker polarity really matters for a single speaker anyhow. So it should work ok even if +/- were swapped.
Also PWM audio is disabled if you're using HDMI out. And the speaker is disconnected if you have headphones plugged in.
The other thing you could try is to verify your board is undamaged, if you have a multimeter make sure that all the marked connections on the board are good (match color to color) in Helder's last image in the support post I listed before.
