Getting no sound from speaker or headphone.

I’ve checked continuity on all audio pins. I’m getting 5v on the 2 GPIO pins I should be getting 5v on and I get continuity on them. However

On the D1 pin pictured I do not get 5v, I’m showing less than 2.

Also on the U2 I think in the other pic, I also do not get 5v on those pins. Do I need to reflow those?

Help just received this boars the other day.

Do you have continuity from the 5v GPIO to the D1 pad highlighted on the image on the wiki? I can see you are not powering the Pi & Controller from the powerboard so you are seeing 5V from the usb plugged into the Pi.

If there is no continuity from 5v GPIO to that D1 pad then there is no sound plain and simple, since it relies on 5V from the powerboard or USB power input to work.

You know what, I do not think there is continuity from the 5v to the D1.

If I don't, where should that be coming from.

If you don't have continuity between the 5v pin and D1, it means that there is no connection which means you need to reflow those pins on the board. All 5 links in the image below need continuity for sound to work.

You guys rock! Reflowed the 5v pins and verified continuity between them and D1 and now sound works!

Thanks so much!
