Okay, so I decided to play the first beta build of Minecraft because I honestly enjoy it as opposed to the newer ones. Anyway, I started playing it and the first thing that jumped out as soon as I got finished building my hut. You guessed it! The door sounds the same as the newer versions. Is there any way I can fix this?
The older versions don't understand the new asset management system, so there is just one single (AFAIK) virtual/legacy layout of sounds for all versions before the new system.
1.0 Beta has the new door sounds.
