There must be a path on Route 214 that leads to Spring Path where trees used to be to pull off this glitch.
The mute Route 214 glitch is a minor glitch in Pokémon Diamond and Pearl that causes Route 214 to become silent. It is similar to the mute Sendoff Spring glitch.
It was fixed in Pokémon Platinum, where Route 214's theme plays in Spring Path and Sendoff Spring, instead of the eerie music heard in Old Chateau.
- You need to have beaten the Elite Four to access Spring Path and Sendoff Spring.
- Go to Veilstone City then go south into Route 214.
- Ride the Bicycle, then go down and right into Spring Path.
- Go into the entrance to Sendoff Spring.
- Go back into Spring Path.
- Go back to Route 214.
The music for Route 214 will be muted until you enter a wild Pokémon battle, go back to Sendoff Spring or go to another route, or go on the Bicycle, dismounting it if necessary (it's possible to go off the Bicycle after going into Spring Path and have the glitch work).
