I have an HP h8-1214 desktop computer running W10 pro. Initially when I would plug a headset into the front audio jack, the speakers that are plugged into the rear jack shut off and all sound came out the headphones. Now, the front jack seems to be designated "communications headphones" and do not get sound when plugged in nor do the speakers shut off. I did not make any changes knowingly, but this just started happening. I've looked at drivers. IDT High Def Audio codec and the "beats audio control panel" but can't find any setting to revert to the old operation. Any ideas????
