The bug

The placement, breaking, walking on, etc. sounds for minecraft:redstone_wire is the same sound which is used for stone blocks. This does not make much sense, as redstone wire is a granular material as opposed to a large chunk of rock. As a result, it'd be expected that the "sand" sound, rather than the "stone" sound, would be used for redstone wire.

This was originally reported under MC-125282, which was later merged into MC-91091. However, many of the cases previously included in that ticket have since been split into other tickets and officially fixed (recent examples include MC-182820 and MC-200484), so I'm giving this one a chance on its own as well. I'd recommend repointing MC-125282 into this ticket as a duplicate.

How to reproduce

1. Obtain redstone dust
2. Place and break it

Expected results

The "sand" set of block sounds would be used.

Actual results

The "stone" set of blocks sounds are used instead.

How to fix

Fixing this is as simple as changing this from the stone sounds over to the sand sounds (or perhaps giving it its own, new, distinct sounds).
