I am using the 2017 Gear VR with a brand new galaxy S8 phone.

While using wired headphones, every time a minecart (on a track or not) moves for any reason the audio starts to distort. If the minecart keeps moving the audio distortion worsens and the game crashes. The audio distortion doesn't happen if a minecart is moving and the wired headphones are not plugged in, however as soon as the wired headphones are plugged in the audio distorts with a moving minecart. The distortion also persists if a minecart moves and the wired headphones are unplugged, making the same distortion with the phone's speaker. The crashes lead to save corruption and loss of progress.

tl;dr Moving MineCarts + Wired Headphones cause Audio Distortion that spreads to all Audio Output and Crashes.
