    I'm trying to help my sister. She has an A7S333 with C-media 8738 onboard
    5.1 sound. She has been using headphones for some time, but decided to buy a
    set of Logitech Z560 4.1 speakers.

    We have tried (through remote desktop sharing) to configure for 4-channel
    sound, but can only get sound through the green line_out jack, even if the
    mixer says that line_in jack is used for rear speakers after configuration.
    We have tried the drivers from Asus CD and those 639 drivers on
    ftp.asuscom.de. No go. All the speakers work, as she can get sound in both
    rear and front speakers (not at the same time) by plugging either of the 2
    cables into the line_out jack (green).
    Is the 5.1 implementation on this board defective? We use latest BIOS and
    the OS is WindowsXP. Is there some trick? We have tried some different
    configs during install, but no go.
    I remember about the same C-media 8738 setup on the A7V333 with 4.1 speakers
    and me and a buddy got that working.

    Your sister doesn't happen to have a PCI display adapter? A7S333 sound
    hates that...

    I have the same board running the onboard sound, however I have never
    set up the system with more than 2 speakers. I did notice however that
    the motherboard has a set of jumpers called BCS1 and BCS2 that you can
    change to change from "bass/center" to "center/bass". The manual is
    quoted as follows on this setting.

    "Use these jumpers in conjunction with the C-Media PCI Audio Adapter and
    to adjust output for 4 or 6 speaker audio. No audio standard exists for
    the three pick-up surfaces on male audio jacks, therefore it may be
    necessary to switch jumpers from the default position, (1-2), to (2-3),
    in order to reroute signals among the internal leads in the line-in,
    line-out, mic female sockets."

    This is at least worth looking into. Hope this helps.

    Update: I got word from my sister today. She told that suddenly all speakers
    worked. We had previously tested the sound with Winamp2. I asked if she used
    WMP9. Yes she did now.
    We went back to Winamp and changed output plugin from wave_out to
    directsound (I have always changed from the default directsound to wave_out
    when installing, because I think it sounds better). Now all speakers work in
    Winamp, too. Guess I have myself to blame, but as everybody knows, guiding
    someone via msn messenger and phone can be hell, especially if it's your
    sister :)
    Thanks to those who answered.
