Yes,thanks for the radarnyan ! ! ! I`m a chinese student,the english is a little poor. I think the reason for this is that we hava 2 even more os in our computuer. if we boot from the other os, eg windows7. so the computer will be somehow affacted,and then we restart our computer to unbuntu the computer will not to reload some software about sounds . so the problem is out.
