Mouse or keyboard gets disabled when sound is playing through USB audio device

[dlund]

Like it says in the title, about 75% of the time I use my desktop either the mouse or the keyboard gets disabled when there is sound playing. It is quite bizarre. I am playing audio through a Audio Technica ATR2USB
My keyboard and mouse are a Razer BlackWidow Tournament Stealth Edition and a Razer Naga, respectively. Each are connected individually to the Desktop motherboard USB ports via a Plugable USB 2.0 Powered Extension Cable. I have tested plugging the devices directly into the computer and the same problem persists.

The bizarre thing is that it seems to come and go with no reason. Some days when I boot up the computer they will all work fine together, others not. And when I use my wireless keyboard and mouse, which both connect to a singular USB input, the problem goes away. Using audio through the 3.5mm headphone port on the computer also doesn't produce this effect (but that's not an option because there's terrible background noise.

Here is my build:
Motherboard: GIgabyte H81M-HD3
CPU: intel i5-4460
GPU: EVGA GTX 980 TI 6GB
PSU: Corsair 860
RAM: 8GB (2 x 4GB) Ripjaw
Storage: 1TB Seagate HDD and 250GB Samsung SSD 850 EVO
Case: Cooler Master N200 Micro ATX
Cooling: x2 120mm XtraFlo fan (Front and back)

Peripherals:
Monitor: Asus VG278HE
Keyboard: Razer BlackWidow Tournament Stealth
Mouse: Razer Naga 2014
Audio: 3.5mm through Audio-Technica ATR2USB

Any help would be greatly appreciated

So four of the six USB3 ports on your motherboard are provided by a separate chip (VIA VL805). That's a totally separate USB controller. I'd be trying different combinations to see if I could isolate the problem. The most likely is that the VIA controller has an issue, so put all your devices onto the native Intel USB ports (use your motherboard manual if it's not obvious which are which - or just use USB 2 ports, which are all Intel on your mobo).

If that doesn't work try different combinations. Try moving everything to the VIA ports, try splitting them between the ports.

There's a good chance you can find a combination that works (my best guess is that all Intel will work fine, but that's no guarantee).

Oh, it's also worth going to the Gigabyte website and downloading the latest USB drivers for your motherboard.

There's a VIA USB 3 driver under the Win 8.1 drivers: http://ca.gigabyte.com/products/product-page.aspx?pid=4674#dl
No Win10 unfortunately.
