Center channel of Logitech Z640 speakers not working with SBLive 5.1 card

[johnyaya]

OK, I'm stumped, for now.

I jut received this Creative SBLive 5.1 soundcard
from newegg.com, and plugged it in to my computer tonight.

I let WinXP do the plug-n-play thing, but also went through the Creative driver install that came with
the CD.

When I run any diagnostics, everything sounds fine - except the center channel. I don't get any center
channel at all. These Logitech Z-640 speakers have a center speaker
that will combine the left/right channels into the center if you only have a 2 or 4 channel sound card, for
example. I've tried it (to make sure the actual speaker is good, and it is), but even with this setting OFF, I still get no sound.

I've checked all the volume controls, SB settings, etc, that all seems okay. The sound works fine running
under Mandrake 9.0 (I haven't tested center channel there yet), but that's not telling me too much.

CD's play fine, but any diagnostic or 6-channel test leaves me puzzled. I don't get it - if everything
is all plugged in, and works otherwise fine, why doesn't the center channel follow suit? Oh, lastly, I've
disabled the onboard audio in the BIOS.

Background info:
Intel 2.26 GHz
Intel 845 m/b
512MB Ram
Onboard sound/video both disabled

Thanks in advance...

Your card set for 4 channel sound looks like.
Control Panel -> Sound and Audio -> Volume Tab -> Advanced-> Set to 5.1

Dependin on OS it may be in deifferent places in Sound properties.

Changing that now...In XP, it was Control Panel->Sound and Audio Devices->Advanced (next to
the image of the speakers. Speaker setup was set to 4 speakers, or something like that...let's
see if this works:

#$#%%...still nothing. I thought that might do the trick (didn't think about changing the
control panel settings). I've got it set to 5.1 surround speakers, but any testing still leaves
nothing coming out of the center channel.

Any other ideas?

EDIT: I am a complete IDIOT. I figured that if the sound worked on some of the speakers,
that I had everything plugged in correctly...well, I didn't. The speaker connection wasn't
plugged into the digital out (only the analog front/rear out, I'm guessing). So that's why
I had no center.

Thanks for your help...be sure to think of me as a moron.
