I’ve double checked and triple checked my head phones and they do work for sure, but not when Plugged into the front jack of two of my computers. One is a HP computer with Win 10 and it works sometimes, but I have to disconnect the speakers from the back.
My other computer with a Gigabyte GA-EP35-DS3 motherboard will not work at all from the front jack and I even pulled the connectors from the Front Panel Audio Header and plugged them back in. the connections on the front jack are soldered and it doesn’t look like there is anything wrong with them.
The front panel cable has 5 plugs. One is a ground with 2 wires in 1 plug and 2 red and 2 white (Line 1R & Line2-L). Only the red wires are used with the white wires dangling. I built this computer years ago, but I never had a need to use the front headphone jack and don’t know if they ever worked.
