lost sound of headphone, Ubuntu 10.10
After several times restart, turn off, turn on the computer, I have found that when I restart from Win 7 to Ubuntu (that means I boot on Win 7, after that I restart to boot to Ubuntu), there is no sound in my headphone (the headphone works for win 7, of course). But when I boot direct to Ubuntu (that means the computer is turned off before), my headphone works. That is my problem.
I had tried with your command, but it said that there is no such file or directory. Thanks very much
