Intermittent Sound Issue with Display Port

I'm having issues with the sound when using a Display Port cable to connect a LG 34" Ultrawide Monitor to my PC via a AMD Radeon R9 390. Full specification of my PC is below.

When I play video's on YouTube I lose sound for x seconds then it comes back and everything is okay until I close my browser. The next time I goto YouTube the issue re-occurs.

When I launch a game I get the same issue.

If I switch to a HDMI cable, the issue doesn't re-occur.

Things I've tried so far:

Re-install AMD drivers for Video Card several times

Changed Display Port Cable (even purchased a VESA Certified Display Port cable)

Changed to HDMI (resolves issue but would like to try and determine the issue with the Display Port)

My PC Specification is:

Intel Core I7 7700K (running at Stock)

32GB DDR3 RAM

AMD Radeon R9 390

Gigabyte Z270-HD3P-CF Motherboard

Currently have 19.5.2 drivers installed.

Anyone have any pointers or suggestion on how to fix?

Have solved the issue. Appears the issue is with the drivers for the High Definition Audio Device, works fine on 10.0.1.7, if I update to the latest version, I get the issue.
