Paintings do not use their unique placing and breaking sounds and instead re-use the item frame filling and breaking sounds. These sounds can be played in game with the commands /playsound entity.painting.place and /playsound entity.painting.break

Step to Reproduce:

1. Get a painting and an item frame
2. Place and break the painting
3. Put an item in the item frame and break the item frame

Expected Result:
The sounds are unique for paintings

Observed Result:
The sounds for paintings and item frames are the same
