No sound on my PC with C-Major Audio Sigmatel

[Guest]

Hi , I'm french , so sorry for my english , I have a problem with my
soundcard , Windows Vista have installed the drivers , all is right with
drivers (I think) , but when I want to hear a song there is no sound , I went
to "Audio Devices and Sound themes" and it shows me some options "5,1" and
"7,1", I have made some test , with "5,1" the speakers "L" and "R" don't
make any sound , but the speakers "SL" and "SR" make sound when I make the
test with "7,1" only RR and RL works (Look at the captures) , the problem is
that I have no sound on my computer exept for those tests ; Thank you for
helping me.
