Skeletons and Wither Skeletons don't make sound when walking

Strays also don't make any sounds when walking.

Every undead mob doesn't make them.

I though that skeletons and their variants were supposed to make clanking sounds when they walk

This issue is related to MCPE-17403; in that bug, however, the undead mobs make player sounds.

After some testing, I can confirm that skeletons, wither skeletons, & strays all DO make walking sounds, but they use the player walking sounds and not their own. Therefore, this issue will now be resolved as a duplicate of MCPE-17403.
