Windows 7: Windows 7 5.1 problem

Windows 7 5.1 problem

Hello everyone, I have a problem with my sound system, and I was hoping that you could give me a give me a hand with it, the specifics:

I have got installed windows 7 64 bits.
My mother board is ASUS P8P67 M B3.
My audio codec is ALC887, directX 11.0 and driver version 6.0.1.6482.
My sound system is Logitech surround speakers Z506.
I did have 5.1 working properly in my system but after some windows updates it stopped working properly, the subwoofer doesn't work although the center does.

When I do the testing in either realtek hd audio manager or windows application, the subwoofer does not sound (center speaker, which shares same cable works) and no the subwoofer speaker works perfectly (it isn’t broken) it is brand new as well as the rest of the computer.

When doing the windows test the green bar goes up and down suggesting that the system thinks that it is actually making noise, when it isn't.

The realtek should let me reasing the jacks just by double clicking on them, not doing so.

I have tried the reassingment fix and all drivers I could find, I have also tried enableling efects and filling speakers and so on.

Any ideas?

Many thaks.

Are you using a hdmi enabled graphics card?
If you are try disabling the hdmi audio on the graphics card.
That solved a similar issue for me recently.

right click the speaker in your tray
pick playback devices
find it in the list (i prefer to only leave the actual playback device I am currently using active myself)
right click it and disable.

3. realtek digital output (optical)

Windows 7 5.1 surround problems (realtek)

give that link a look over and see if any of the suggestions help you.
They apparently went through a lot of trial and error there and I'm hopeful something in that mess will be of use to you.

yeah I would have other ideas as to what to try if there was a complete failure but just the loss of the one channel is very odd.

One last thing that occurs to me though it seems unlikely is that there is actually an option to swap the mic in for the center/sub out in the windows options under speakers -> properties (located in the same place as the above suggestion)

It is possible this option needs to be checked on your system. I can not say for certain not knowing how this specific system is set up though.

It could be that an update reset the configuration. In the Sound window, Playback tab, right click speakers and select Configuration. Verify your setup and test each speaker. Also, you might want to unplug all the speakers then reconnect. This has cleared "lost" speaker problems too.

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.
