The problem persists. The motherboard has two adjacent ports for front panel audio; one marked "HD" and the second "AC97". The single cable from the front audio jacks has two connectors at the end; one marked "HD" and the other "AC97". If I connect the cable end marked "AC97" to the port marked "AC97" and set the BIOS for "AC97 front panel", should I expect everything to work? I'd have HD audio at the rear ports and AC97 at the front? That would be fine as I only expect to be using headphones at the front from time to time.
