[dongjin kim]

hi there...

I met a problem on windows 7 sound system...

when i click mouse left button on sound icon of right lower corner, it didn't work ...

so i clicked right button on sound icon and then i opened control option window of sound...

i found sound jack led on state...

but as soon as problem solve process continues , there was a massage of "there isn't a joining of sound speaker ....".

so i have a question of microsoft error message system...

what did it happen anyway...?

system state is mal state...

i am confused...

is microsoft windows incomplete ?

i don't know the reason...

whom do you know knowing of this state?

please give me an answer...
