rplatham Sept 28, 2016 I've hijacked this ticket and generalized for all things that incorrectly give the stone sound when being broken:
item frames all wood stairs
Other things with incorrect or missing sound (from duplicate
- wither boss sounds (HAVEN'T TESTED)
- lead sounds (no sounds as of 18.104.22.168)
- some shulker sounds (NOT SURE)
Item frames make the wrong sound when you break them (stone sound). In PC they make the same sound as paintings when broken.
