I have Windows 7 on my laptop and yesterday I created a partition for Ubuntu. All was right, but I noticed that when I try to hear music from my headphones on Windows I could not do it. In Ubuntu there was not any problem, only happened in Windows. I can hear music from my laptop's speakers, but not from my headphones. Also I can record form the microphone that is in my headphones. The only problem is hearing sounds with them. If I turn on my laptop with my headphones previously connected I can use them without anyproblems in Windows, but if I turn it on with my headphones disconnected then, when I try to use them I can't. Can anyone help me with this? Thak you all.
