Sound comes out of my speakers even when headphones are plugged in
I just wanted to listen some music on my Notebook (Ubuntu 11.10), so I connected Headphones, and started Banshee. But later noticed the sound really came out of my headphones and my speakers.
I tried to fix it with Audio options, but I couldn't way and it isn't a Banshee bug. I'm using a Medion MD 96630, here's a chart with its stats and it has a HDA-Intel-Chip with Realtek ALC888 Codec
Thanks to anyone who can answer me this, and please give me a detailed tutorial how to fix this.
