I just got a new Toshiba machine, with Intel I3 processor with integrated graphics. I was disappointed that on Windows 7, all HD video, and even DVD's have a poor refresh rate and thus look a little stuttery, even with 3GB ram. Ubuntu is running fine, and shows crystal clear picture, only problem is that I can't get Ubuntu to recognise either the inbuilt mic or the headphone socket. Can anyone help with this? I am running Ubuntu 10.10

Thanks.
