This is odd. I have a cheap 2.1 set of altec lansing computer speakers that don't buzz when I game. (typical connection - just the 3.5mm headphone jack). My headphones don't buzz when gaming. Over Black Friday I bought a pair of JBL 306 MK2 monitors. I was excited to use them on the desktop, and they work fine while using the PC on the desktop, but when I use them during gaming (when my 1080TI is under a workload) I get a nasty loud electrical hum/buzz that’s loud enough to easily hear over game sounds and varies in pitch slightly as I use the mouse to look around, or as the game scenry (FPS?) chances. When I exit the game it goes away, and it's back to only the slightest of hiss from the active speakers that you have to put your ear close and actively listen to hear. Alright, I thought, maybe it's the onboard soundcard on my X99 Gigabyte Ultimate Gaming. So I tried connecting my USB based Blue Yeti Mic's DAC (and disconnecting all analog audio output from the computer) Same exact problem!!!? What? The Yeti has a external USB DAC!!! Confused, next I tried going back to an old external OPTICAL connected Turtle Beach USB powered DAC. There is no analogue signal on this either - it uses toslink optical to power it. Would you belive the same thing happens?!!? It's not a proximity thing - because when I unhook everything from the speakers and just have them powered on they don't buzz/hum when the 1080TI is under load/in game. This doesn't make sense to me at all... Any ideas?
