Hello guys,

My computer is with windows 8 operating system now. All things are fien. But last evening, when I switch on the stereo connected to it, there was no "bang"sound as usual. When I played the music, it also gave me no sound, even if I adjusted the volume to the loudest. As a computer novice, I have to turn to you for help in case of any little problem.

Pls forgive me and do me a favor!

Thanks a lot!
