Windows 7 5.1 problem

thanks carwiz, replugging did not fix it nor reconfigurating, i'll google lost speakers...

This happened in between working 5.1 and not working 5.1

"There are several well documented bugs in the Windows 7 RC build. The bug appears when a hardware/software component fails to re-initialize when the system resumes from Sleep or Hibernation or will not enter the suspend state. This is a small list of other issues that have been seen. These bugs have only been seen on specific systems that have combinations of certain hardware/software installed."

Don't know if related or hwo to fix it...(not gone into hibernation/sleep in a couple of weeks)

did find it...it is wierd that center works and sub doesn´t coming the signal from the same cable.

I edited my post after seeing this. Did you read the "EDIT"?

EDIT: There is a setting you need to use when a sub-woofer is combined with other speakers on the same connection. Otherwise, the sub-woofer is assumed to be stand-alone and the driver will chop the low frequencies from the output for other speakers. I just can't think of it at the moment but it is part of the Configuration.

I understand waht you are saying but I don't know what to do next, I think I have tried every possible config...any ideas.

Thank again

One more thing, there is an option to flip center for sub and vice versa, when I do change it, the center sounds when it is the subw is highlighted and when the center is highlighted the center mutes, which reinforces your theory of the lower frequencies being shut down...don't know if I made myself clear

Here you go.
Set your Configuration to 5.1, click Next.

Un-check the Sub-Woofer box. (Turn it off.) Click Next.

Check both boxes for Full Range Speakers. Click Next then Finish.

It doesn't work, it stay mute, but if in addition in realtek I check the box switch center/subwoofer, the subwoofer stays silent but the center plays the bass THIS IS MADNESS!!

Many thanks for your efforts.

PD: I am going to bed, it's 4:15 am in Madrid...TEXAS FOREVER!!!

I just read that my speakers are not real 5.1, but virtual/3D 5.1...

Ok, but it did work at some point just before some major win update...
