How to clear the notification 'Analog audio accessory detected' in Pixel 2?

[Android Central Question]

I don't know what I did today, my google pixel 2 just sudden has this notification from android system

"Analog audio accessory detected
The attached device is not compatible with this phone. Tap to learn more"

I actually don't have any attached device, I can't clear this notification or disable it. Anyone know how to fix it? Thanks,
