I'm trying to help my sister. She has an A7S333 with C-media 8738 onboard\n5.1 sound. She has been using headphones for some time, but decided to buy a\nset of Logitech Z560 4.1 speakers.\n\nWe have tried (through remote desktop sharing) to configure for 4-channel\nsound, but can only get sound through the green line_out jack, even if the\nmixer says that line_in jack is used for rear speakers after configuration.\nWe have tried the drivers from Asus CD and those 639 drivers on\nftp.asuscom.de. No go. All the speakers work, as she can get sound in both\nrear and front speakers (not at the same time) by plugging either of the 2\ncables into the line_out jack (green).\nIs the 5.1 implementation on this board defective? We use latest BIOS and\nthe OS is WindowsXP. Is there some trick? We have tried some different\nconfigs during install, but no go.\nI remember about the same C-media 8738 setup on the A7V333 with 4.1 speakers\nand me and a buddy got that working.
