Why has the volume on my Sky+ HD box suddenly gone very low?

[darkntwisty]

I've had the box for nearly two years now and haven't changed a thing in that time. Over the past two days the volume when watching Sky has become increasingly lower until it's now at the point where it almost has to be at 100%. Not only that, but as my television came with built-in Freeview, when the volume is up that high when the Sky box is turned on, you can hear the Freeview audio.

Has anyone else had this problem? Any ideas on how to fix it?

(There aren't any volume settings through the Sky menu, which isn't very helpful.)

I have the opposite problem, on sky multi room box when I turn on volume is at 59 to 60 deafening I have to mute to get sound sorted help needed as well.
