abb-codec: ABBamp 2.4.5
Normally, we use "mute all sound" in system settings to disable all sound.

But the earpiece is also disabled, when a call comes, it will take us several seconds to enable sound in settings.

So I add a interface to disable speaker ONLY.

I think it's for me at least.

What's more, this update edits some messages and fixed some bugs.

Check the previous commits.
