Random "Input" Notification Tone

[cliuless]

I've installed iOS 11 on my iPhone 7+ and I keep getting the "Input" notification tone randomly. There's never an accompanying banner and I can't figure out what it's supposed to be attached to. I don't have it set as a notification for anything that I can find. Is anyone else experiencing this? Any ideas on a fix?

Under Sound Settings, do you have anything set to Input?

No, I checked that first. None of my notifications are set to Input.

Well, that leaves me cliuless.
