lg ultrafine display 5k 27 microphone static

I've tested the audio with the LG mic, the MacBook Pro mic, and external mic (iPhone earbuds with mic) with both Zoom and WEBEX, and the static is always present with the LG mic, never present with the MBP mic or the external mic. I called LG and they've sent me an authorization to return the monitor. I've only had the monitor for 3 weeks but I can't return it to the Apple Store at which I bought it - about 40 miles away - because it and all the other Apple stores within about a 4 hour drive are closed due to covid-19 constraints (I'm in SC). You're pretty much on your own in these circumstances. There's a "warning" on the Apple web site, but it's hard to believe you can spend $1200 on a product promoted by Apple on the Apple Store website as the perfect accessory for your new MacBook Pro and then be sent to the manufacturer for resolution of your problem. In the future, I would not recommending buying any expensive accessory from Apple that is not branded Apple. A real wake-up call for a guy that has bought at least one of every consumer product Apple has made since about 2004.

Did not solve problem. See post by fourspace from 7/23/2020. Same issue.
