Nexus 6 odd sounds out of no where

[AC Question]

Ever since yesterday evening. My nexus 6 has been giving off this weird notification sounds even when nothing is happening. It's completely random and I did some research. Found that a person on YouTube has replicated this issue and had it recorded.

I'm not allowed to post the link but if you go to youtube and search "Nexus 6 odd sounds" you'll find it.

Anyone got any ideas on how to resolve this?

Welcome to Android Central! I saw another post about that a while ago: http://forums.androidcentral.com/as...s-5-makes-weird-sound-can-anyone-help-me.html. Couldn't figure it out. Doesn't seem like an NFC notification, and I don't think it matches any of the preloaded notification tones.
