[linux-audio-user] meters with resettable infinite peak hold

not quite..... on input strips, while recording (when the signal never  
goes over because it's limited by your A-D), the numerical peak display  
only goes to "-0.0" and never turns red. at least that's what i'm seeing  
here (0.9beta28).

and, yes, i did change requirements mid-stream, by adding "reset ALL".  
good catch!  :)
