Hi, when my headset is plugged into the STX, opening up any game will cause a buzz from the mic output. I can't hear the buzz through the headset, but my friends on teamspeak can definitely hear it. I confirmed the problem via recording myself while in game and listening to the playback.
~Here are some things to note~
1. I recently upgraded my system and the issue is only apparent in the new build, the old build ran with no issues.
2. Windows 10 x64 was the os in both builds.
3. Bios/drivers/windows are up to date.
4. Using UNi Xonar Drivers for the STX.
~Here are the specs for both builds~
Old build
CPU: i5 2500
GPU: Gigabyte GTX 980 G1 Gaming
Motherboard: ASRock Z77 Extreme4
Memory: Kingston 8 gig ddr3
Storage: Seagate Barracuda 2TB
SSD: Samsung 840 PRO
Case: NZXT Phantom 410 Mid Tower
Power supply: Corsair CX750M
New build
CPU: i5 6600k
GPU: Gigabyte GTX 980 G1 Gaming
Motherboard: ASUS z170 Pro Gaming
Memory: Corsair Vengeance LPX 16gig DDR4
Storage: Seagate Barracuda 2TB
SSD: Samsung 850 EVO
Case: NZXT h440
Power supply: Corsair CX750M
As you can see, I kept some of the components from my old build. Here are the things I've attempted to fix the issue but to no avail.
I've tried to be as specific as possible but to be honest, I just feel like it's a problem with the motherboard or it's a driver issue with the STX and ASUS has not bothered to update the drivers for this specific card other than to just release a version that's compatible with windows 10. I will probably just buy a DAC in the near future.
Thanks!

Disabling onboard audio.
Disconnecting front panel audio from motherboard.
Reinstalled to windows 8.1
Use the headphone jack of STX and mic jack of the motherboard. I could now hear the buzzing through headset.
Tried it the other way around, same result.
Bought a USB audio adapter and connected the mic to it.
Tried a different power supply.
Connected all power plugs to one power strip.
Move STX to the furthest pci slot from the graphics card.
Resit all components.
Mic works fine when both mic and headphone input are plugged into the motherboard.
