Ignored, with "out" (5)
I believe the answer is:
tuned
'ignored with out' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tuned that I've seen before include "(Of a piano) properly adjusted" , "arranged for reception" , "Of engine, adjusted to run properly" , "Correctly adjusted (eg in pitch)" , "Adjusted (musical) pitch" .)
