Changing the mipmap levels under video settings will stop minecart driving sounds while nearby or riding in them.
What I expected to happen was...
The minecart sounds keep playing after changing mitmap levels.
What actually happened was...:
The sound stopped playing.
Steps to Reproduce:
1. Sit in, or stand near a moving minecart and change the mipmap levels.
2. If you notice, the sound will stop playing.
Edit: Cannot confirm. Sound stays on after decreasing and after increasing the mipmap levels.
After having this issue: Please attach the complete output of the "Game Output (Your Minecraft name) " which can be found on the fourth tab of the launcher to this ticket.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".
