Bumping an old thread. In looking at your picture closer, it seems you may have excess solder on the ground pin. This, itself, isn’t an issue. But if you also have excess solder on the Audio Pin, which is the 1st pin on the second (right side) pin header, then you could be bridging audio to ground. This will cause a buzz even if the SID is removed. I would check continuity from pin 5 audio to ground. There should be none. If it’s shorted, then there’s your problem. You can also check it at C13. There should be no contact to ground.
