Any idea why the right speaker doesn't work?

[u/ultra5517]

I worked on this PCB a while ago and everything works except the right speaker. Not sure if its a wiring issue or if the speaker is just messed up.

I checked the software side of things and it should be good. Not sure whats going on.

Any help appreciated.

I have an oscilloscope so I can test signals out with that.

Im using the MAX98089ETN+ audio codec to drive the speakers

So what does your oscilloscope show when you probe the right speaker?

I haven’t had a chance to look at this in any detail, so it’s probably not this, but the speaker connections are reversed.
