There are 2 more tests that can clue us in on what might be the problem.
1) While there is a game playing, can you adjust the volume knob and put pressure on the disc/wheel? Does that make sense? If there were a problem with the wheel itself, this might cause the volume to actually sound correct (like while you're pressing down on the wheel).
2) Use headphones. Does it sound really good when you're using headphones? The headphones do not go through the amplifier/speaker, so this can be a good clue as to where the problem is coming from.
If I'm remembering the different speakers correctly, that speaker is not one of the batch we thought might be flakey. I'll make sure about that and get back to you in a bit.
Also: Are you running on Pi Zero or Pi Zero W?
1. So I did notice that there was slight pressure still on the volume wheel when trying to spin it. I cut back the case a little more and it sounds much better! Before, the game sounds was completely drowned out by the white noise. There is still some noise but the game sound is coming through much stronger at this point.
2. I did try headphones and it sounds perfect when using them. There is no white noise produced when using them at all.
Its very likely this could all be an issue of a bad solder connection on my part, so I did include the photo requested. My joints are all but good and I really need a new tip for these smaller connections. Let me know if you see a connection that may be the culprit and I will redo it. I am using a Pi zero and should be getting a wifi dongle today and will be able to try step 4 on the document you referenced. I will let you know later today if that cleans up the audio.
