When you are in an inventory ("E" inventory, chest, and enderchest) and you exit out of the inventory it seems to "pause", "refresh" or "mute" the sounds system. Then resumes shortly after.
You can reproduce by spawning chickens next to you (preferably a lot 😛 ) then place a chest right next to the chickens and open and close the chest. Also you can open and close your inventory. (E)

Cannot confirm, can you describe it differently? Are you experiencing multiple sounds playing multiple times, echoing, or overlapping?
