Headphone Jack Works, Speakers do not

Thank you for the awesome project! The Makerbuino was an amazing build! After completing the build, the headphone jack works perfectly fine. However, the speaker does not work. I would love some help. Thoughts?

Hey there,

Thanks for coming to our community!

As I see on your board, some of the solder joints are not done properly and need to be reworked. Every single joint needs to be nearly perfect in order for everything to function properly.

Please try to fix as many of them as possible in order for the speaker to function.

Here is an example of some good soldering.


Thank you so much! I reworked all the joints, and the sound is working now! Awesome!
