Hi. I did a search and found out that this bug has been in the game before but it was years ago. But its back in 1.17: whenever i use an anvil, the sound random.anvil_use doesnt play. i checked and all other sounds are working. it still plays if you use /playsound. 

How to reproduce

Repair or rename or enchant anything using an anvil and no sound will play upon picking up the item out of the slot
