How do I turn off "USB connected" notification sound?

[Android Central Question]

I have an LG G6. I had another and the screen cracked so had to replace it.

I don't ever recall this being an issue with the old phone but with this one, every time I plug it into a USB cable it beeps at me. I can't find a setting to turn this off.

I've turned off every "system notification" sound that I could find, since I only want my phone making noise when I get a call, text, email or calendar appointment.
Help?

Why would you want to turn off the USB connected sound indicator -

It's to tell you that it's connected to the computer correctly -

as in: Charging Only - or - Power Supply - or - File transfer - or - Photo transfer - or - MIDI device
