    Z690 Hero Audio Impedance Sensing Issue

    I have an issue with my motherboards Impedance Sensing. It is way off setting my headphone to over 1000 ohms when my headphone are rated 150 ohms. Pushing high amounts oh power into my headphones could cause damage.

    I have tested the headphones on two of my other Asus motherboards and they are detecting the headphones correctly setting them to 150 ohms not popping and cracking etc.

    I have also tested two other headphones that are rated at 30 ohms but this motherboard is pushing far too much power into them causing them to pop and crackle. I have tried reinstalling windows 11 I update my drivers using the motherboards Armoury Crate

    I am using Realtek Audio Control driver version 6.3.9600.2299 UI Version:

    I updated all my motherboard drivers using the Asus Armoury Crate.

    Is this a known issue and is there a solution ? I have added a screen shot of the impedance setting it is forcing me to use.
