Just recently assembled my CM3. First attempt, so had some challenges with the build, but happy with it for the most part. I am having an issue with the speaker. I wouldn't call it white noise. It's almost a rhythmic buzz or squelch that doesn't start immediately on boot up. I usually have to start a rom or sometimes even going into the retropie-setup menu causes it to start. Once it begins, it will keep doing it. When I initiate a shutdown, it will make this noise constantly until it turns off. Otherwise, it's not always constant. There are short pauses in between, with the buzz lasting 2-3 seconds. I can reproduce this with the guts completely removed from the case and not touching each other. I don't hear it thru headphones. Kind of at a loss on this. Any suggestions?
