The soundpost is in the right spot, the bridge was fine, the pegs are okay a little bit slippery but peg drops can fix that, the strings I would recommend changing

The sound post was not in the right spot - it was under E string instead of under A string - it could have been too long or got shifted during shipment, which is common

He recommended a few changes: 1. to replace the sound post that is too long and not in the right spot, 2. to change the steel strings that came with the violin with Dominant strings, 3. to cut a new bridge, the current one is too thick and too low (a thick bridge would dampen the sound)
