audio Audio Crackling When Using SteamVR

[The Mighty Spoon]

Since around 2 weeks from now i have started to experience Some really bad audio distortion/crackling whenever i start up steamVR and have sound play though my Valve Index Headset.
Whenever this happens i also notice that the windows audio device graph isolation prosses in Task Manager suddenly starts using more and more CPU, up to over 35% in some cases (it is normally at around 0.1-0.5%)

What i have tried

• Swapping around what USB ports the VR Headset is connected to
• Re installing SteamVR
• Re installing audio drivers
• Re installing graphics card drivers
• Re installing windows (not a clean re install, kept the programs/files/documents)
• Uppdating to the latest version of BIOS avalible (Version 3003)
• Tried windows troubleshooting
• Contacting Steam Support (no answer yet from time of writing this)
• Restarting the computer several times
• Disabling windows audio enhancements where possible
• Un checking "Allow applications to take exclusive control of this device"

So far none of these suggested fixes have worked.

Specs

• CPU (AMD Ryzen 3 5900X)
• GPU (Asus GeForce RTX 2070 Super ROG Strix)
• RAM (G.Skill 64GB (4x16GB) DDR4 3200MHz CL16 Trident)
• PSU (ASUS ROG Thor 1200W)

• Boot ssd (Toshiba-TR150)
• NVMe drive (Seagate FireCuda 510 SSD)
• OS (Windows 10 Home)

 

I have attached some screenshots that i hope is able to add some relevancy to what I'm talking about.

I have narrowed it down to possibly being an issue with the Nvida High Definition Audio Driver.
