Dear ROG community,
Since I switched motherboards from an Asus Z170 Pro Gaming to the Maximus VIII Ranger two days ago, I have been having similar issues as the person in
https://rog.asus.com/forum/showthread.php?82116-Maximus-VIII-Hero-front-panel-audio-noise&highlight=...The frontpanel headphone connector gives audible white noise, pops and high-pitched squealing through the headphones. While this wasn't the case with the previous Asus motherboard. If I plug the headphones into the headphone port, as soon as it has detected impedance, it starts giving off the noise. This noise comes exclusively from the headphone port. It's there regardless of what I'm doing with the PC.
I have tried plugging the headphones into the mic port and selecting 'headphones' in the Realtek HD Audio Manager, this lets the headphones function without any issue. The impedance detection on the headphone port results in 33 ohm and then squeals. Whereas the microphone port detects the same headphones as 926 ohm and remains dead silent.
Even though I'm 98% sure this issue wasn't there when I was using the Asus z170 Pro Gaming, I tried rerouting the HD audio front panel cable, clearing it. But to no avail. I've also attempted to reinstall the audio drivers from the Asus website. The solution provided in the thread I linked to above did not work for me, as I have never installed AI Suite. Using the Windows High Definition Audio drivers results in the same squealing noise coming from the headphone port.
Any indications on how to solve this issue are much appreciated.
Short recap:
- Squealing through front panel headphone port (33 ohm impedance detection)
- Quiet and functional if plugged in front panel microphone port (926 ohm impedance detection - same headphones)
- Rerouting/isolating the HD Audio cable has no effect
- Using the Windows Audio drivers has no effect
- Problem not present or unnoticeable when using previous Asus Z170 Pro Gaming motherboard (no longer in my posession, currently waiting for a friend to bring over his PC so we can double-test his mobo+case front panel with mine)
System:
- Fractal Design Define R5
- Corsair Rm650x
- Kingston HyperX Fury black 16GB
- Intel i5 6600k
- MSI GTX 970 4gb Gaming
- Sennheiser HD 438 Headphones
- Windows 7 64bit
- Latest drivers from Asus websiteEDIT:
Tested the motherboard with another case's HD Audio cable, completely clear of any other cables or components, the squealing persists.
