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' means one lot of letters go next to another.
'very' becomes 'so' (both can mean 'extremely').
'engaging' means one lot of letters goes inside another (inserted letters are engaged or involved in others).
'summit' becomes 'peak' (mountain peak).
'so' placed around 'peak' is 'speako'.
'f' put after 'speako' is 'SPEAK OF'.
