Audio sync issues RHEL8 Workstation install

Hi all.
I'm running RHEL8 on a Thinkpad X1 6th (I7 16GB)
I'm having some issues with audio / video sync - in both conference calls and when playing videos in a browser, for example in Youtube.
The video and audio are dramatically out of sync.

I've had Fedora 28 on the system previously and not run into the same issue. Any ideas?
