I am running LMDE update pack 4. Everything is fully up to date, my microphone, webcam and everything else works. The only thing that doesn't is my heaphone socket; when I plug my headphones in - nothing, I have checked all the sound/mixer properties and cannot find a way to enable my headphones. They work fine under Mint 12, plug it in and I get sound but no matter what I try I can't get the same to happen under LMDE. Someone please help - this is the only thing stopping me using LMDE. Thanks.
