Hello! Some time ago i posted this https://rog-forum.asus.com/t5/overclocking-tweaking/problems-with-x870e-hero-motherboard-and-expo-pr... and i managed to provide a temporary fix seen in the video. Eventually ASUS engineers managed to fix the problem after releasing few BIOS updates. Unfortunately new problems emerged recently. After updating my BIOS to 

Version 1805

I started experiencing stutter everwhere,  youtube videos, video games, especially in war thunder and BF6 , pretty much all games have some type of a stutter. Sounds almost like a static through my headset, ill provide a video in the comment section. ASUS guys, I mean.. Cmon...

Hi @CptMario 
Same board here, no stutter. Are you referring to audio stutter or are you experiencing frame time issues in games, etc?

Can you try UEFI 1901 (beta)? Contains newer AGESA FW.

Please list full system specs, inc any devices connected via I/O.

Have you checked tools such as Latencymon?

Im referring to audio stutter and a micro stutter accompanied with audio stutter, that happens in battlefield 6, war thunder and pretty much all games. I wasn't experiencing that before. I will gladly test the newest bios and report how things went to you.

I would try the BIOS I linked, as this contains the most recent AGESA.

So far the audio stutter was reduced by 80%, ill continue testing and report back in few days, latest BETA bios seems good.
