Motherboard audio static on msi gaming 7

[Amir Castleberry]

I've had my newly built pc for about a month now, the sound has been perfect since day one but since about two days ago my audio started to sound like crap, all of a sudden every time theres audio playing whether its a video, music, or game the sound is distorted with buzzing and static sounds but when theres no audio i hear no static, i've ruled out it being a headset issue because ive tried multiple headphones and speakers and they all yielded the same results. Please help. :c

Hello,

First, unplug the front audio panel from the motherboard, then test all the outputs from the back panel; your Realtek software can re-route the output signal to any jack by using the Auto Sensing feature, so if the main output, Line/Front Out, is broken, you can use the Rear Out or C/S Out instead (of course, the audio signal will not be the best when using headphones, as the main output has a built-in headphone amplifier, but for a set of active speakers it will be OK). Also, disable any kind of digital audio output (SP/DIF or HDMI), uninstall NVidia HDMI Audio Driver.

If no result, turn OFF the PC, unplug it from mains and check if all the connections from PSU to motherboard/CPU/GPU/HDD/SSD, etc are OK.

If still no result, you should consider a PCI/PCIe audio card, an USB audio card or an USB DAC; it will be better if you can borrow one just for testing, because it's possible that the motherboard got broken. Don't forget to disable the built-in audio card from BIOS.

I had a problem with hiss on my x99 s sli.
there is a volume slide in my realtek settings near a microphone boost slide. When I turned it down the hiss went but my audio channels played fine so I am unsure what audio channel it was boosting.
The hiss was not affected by changing any of the settings in windows audio settings so it was specific to the realtek settings.
