When the volume is below 0 db, and I want it at 0 db, then I usually hold the volume button on the remote until it automatically stops on 0. It stops like it should but it keeps beeping. This can be annoying cause often I want to turn it up to 0 without having to look at the display. Similarly, if it's in (overdrive) and you hold down the volume button, it'll beep nonstop but the volume won't go anywhere. I like the volume working like that, I just don't like the unnecessary beeping. And it also beeps when you try to turn it up past 10 db.
It's not a big deal, but personally I just think it should beep only when the volume actually changes, not just every time you push the button.
