Discuss loudly after very engaging summit (5,2)

'discuss' is the definition.
(I've seen this in another clue)

'loudly after very engaging summit' is the wordplay.
'loudly' becomes 'f' (short for forte - 'loud' in music).
'after' is a charade indicator (letters next to each other).
'very' becomes 'so' (both can mean 'extremely').
'engaging' is an insertion indicator (inserted letters are engaged or involved in others).
'summit' becomes 'peak' (mountain peak).
'so' going around 'peak' is 'speako'.
'f' put after 'speako' is 'SPEAK OF'.
