Just recently built a new machine. It uses a Gigabyte Z87X-UD5H motherboard & I'm using Windows 7 64-bit home premium.
When I have my headphones or my speakers (occurs with both) plugged into the rear line-out audio port, every few minutes I get a message from windows saying that the device has been unplugged & then plugged back in. It's nearly instant, just a little flicker in the audio & the message - so quick you don't even notice it half the time.
The front audio port on the case does not have this issue, it's only happening with the actual motherboard's back panel. If I plug into the front panel the sound is flawless.
Does anyone have any suggestions what might be causing this? Is it likely to be a hardware fault with the motherboard, or is it just windows getting freaky?
My CPU & graphics card temperatures seem solid. CPU normally at ~30c, has peaked to 55c while encoding a movie. Graphics card is at very similar temperatures.
The top fan in the case wasn't running at all at first but I swapped its plug & now just seems to be running slightly slow - HWMonitor reports fan1 at ~560rpm, fan2 at 270rpm & fan3 at 180rpm. Other than that everything seems normal.
Full system specs are: i7 4770k, Gigabyte Z87X-UD5H, Asus GeForce GTX 780 DirectCU II OC 3GB, Seasonic 750W gold power supply, 16gb Corsair Vengeance Pro RAM, Noctua NH-D14 cpu cooler, HAF X full tower case, Samsung 840 EVO 500gb SSD & Western Digital 2tb Caviar Black HDD.
