I have a red/white RCA to 3.5 cable plugged into the line out jack on the board, the board's HD audio is enabled via bios, but no sound. I tried the other 5 jacks to be sure I had the right one but no luck.
Gotta be something we're missing. When window's payback settings window is open & realtek sound enabled, it's sound meter moves with the sound. So it detects the sound & also detects when a device is plugged in.
