I have this weird issue with static/distortion on the left channel of any headphones using the onboard front HD audio header/port. The port on the I/O panel works fine. If i change the bitrate to 192k 24 bit or 192k 16 bit the noise goes away. its only present at the default 48k 24bit and the 48k 16 bit options. i tried connecting a different front audio panel to the header to see if it made any changes but it didn't. You think this is a defective board or just a software/hardware issue
