The speaker wire should usually be routed around the "outside" of the PCB. It looks like you have it running toward the battery compartment. This can pinch the speaker wires and maybe cause the issue you're experiencing.
That's an older photo, but I would suggest placing the speaker down first. Notice that the wires are pointing toward the outside of the shell (away from the battery compartment). Then you can lay down the PCB and the LCD. On the new board (the one you have), you can then plug the speaker into the main PCB.
Another thing to look for is on the PCB "underneath" the speaker jack and the volume wheel. These two components have legs that stick through the PCB. Sometimes their legs are too long and they can contact the plastic. You can snip the protruding legs off, and you can snip off the plastic that they contact.
Another thing is that the PCB you have, as you may know, is from a new batch. There are some new mods/features on it, and you're helping to uncover some areas where we need to update our documentation. There is now a post that must be snipped off. I have circled it in yellow (on your photo) and I've grabbed it with a tweezer on my other photo. In the pre-2019 PCB, there was a hole for this post. Now, the post must be shortened instead of protruding through the PCB.
I'm sorry that I didn't reply yesterday. Maybe you already found the solution.
