I tried both headphones and speakers and I plug them correctly I am sure. I can't hear anything and I can't record my voice either. here is the snapshot of my device manager
I am newbie about windows 7 before,I had win Xp I think I should install drivers but I don't know what should I search and install also I don't have my driver CDs
what can I do?
is it possible that maybe my settings have problems and the drivers are installed perfectly?
