Nor am I, and I fully expect someone to chime in here anytime and say "if ya don't like it, send it in for repair, CLOSE THE THREAD"... eventually the sheep will stop drinking the Kool-Aid,
As it should be. There's a sticky with information for those that have the issue. Creating or adding on to a new post doesn't help the situation. The part that Uniden sends to you "mitigates" but doesn't "eliminate". I'm not sure what you are looking to do here...but if the intent is some sort of mass recall, don't hold your breath.
I saw your video, and with all my scanners running at the same time, barely heard it. Checked in a quiet room and yes heard the "processor noise" similar to when my computer boots up. Sheep we are not, but informed consumers you should be. Options are always to return a defective scanner, order the part and do it yourself, or send it in and let Uniden install it for you.
In some of the videos by members, I noticed a difference in speakers too. I'm no electrician, but if you're trying to make it sound like a firehouse speaker, then yes I'd expect the noise to be more. Home electrical systems could be the culprit too....I don't know. But..as in the sticky, the issue has been acknowledged, a fix has been offered and not much more to be done here. Hopefully the moderators will look at this post and lock it as well as it's just a repeat of the sticky...
