New Build, No Sound

[mdonova3]

Here is a build that my fellow forum members helped me come up with. It is assembled and all seemed well until I plugged my headphones in the front jack - no sound. I tried them and a pair of speakers (all working in other systems) and still no sound. I have updated my drivers and tried all logical and obvious settings checks. However, when I use a monitor or t.v. with hdd (plugged into my Radeon GPU), I get sound. Is the Radeon card circumventing my motherboards on-board sound?

Case: Cooler Master HAF 912 Mid Tower

CPU: Intel Core i5-2500K Processor

CPU Cooler: Cooler Master Hyper 212 Plus 120mm Sleeve CPU Cooler

DVDR: Asus 24xDVD±RW Drive DVD-RAM

GPU: SAPPHIRE AMD Radeon HD 6870 1GB GDDR5

HDD: Crucial 64 GB m4 2.5-Inch Solid State Drive SATA 6Gb/s CT064M4SSD2

MOBO: Gigabyte Z68A-D3H-B3 ATX LGA1155

PSU: Corsair Enthusiast Series 750 watt

RAM: Corsair Vengeance 8 GB ( 2 x 4 GB ) DDR3 1600 MHz

make sure that your front panel audio cables are connected to your motherboard inside it sounds like there not, if thats not the case then it could be a bad 3.55mm audio port though id put money on it either being plugged in incorrectly or not at all

forgot to add that your hdmi port on your graphics card is also an hd audio port even the 5000 series have this feature its not circumventing though

And of course make sure you installed the Realtek audio driver.

There were two different connectors on the Cooler Master 912's audio attachment. I had something labeled "AC 97" plugged into the motherboard, but I should have had the "HD Audio" plugged in. Thanks for the help...
