This issue currently involves random Respawn Anchor charge noises that play in Basalt Deltas specifically. Although they are quite subtle, turning up the volume should greet you with this issue.
How to Reproduce:
Simple, enter a Basalt Delta Biome and listen carefully for random Respawn Anchor noises. Even if you're not charging a Respawn Anchor yourself in this biome, you should still be able to hear these sounds.
Extra Note
I believe this also affects Windows 10 versions too. They might be the result of an error that occurred while trying to get the ambience for the Basalt Deltas, but there's a chance I could be wrong.
Observed Results
Respawn Anchor noises play every now and then, in a rather low volume.
Expected Results
The Basalt Deltas are expected to house moody ambience and is expected to sometimes play the soundtrack "Lena Raine - So Below".
Quick correction I have to make - I mispelled Biome in the How To Reproduce test. My mistake!
