X-fi - no sound from speaker

Hey,

I have X-fi Fatality, Win XP, Creative 5.1 speakers (5200) and I have the latest drivers installed.
Everything was working perfectly fine, until a few days ago, when I bought Nvidia 8800 GTX graphics card and installed it on my Nforce 4 A8-NE card.

Now I can only hear the left front speaker, center and the left rear speaker. When I do the test, I hear "LEFT front" and "RIGHT front" from the same left front speaker. The same is with the rear one. The cables are fine, I checked them and tried switching them, the speakers are fine as well. I tried re-installing the CD drivers, then the latest drivers, nothing helped. I tried reinstalling graphics drivers and chipset drivers as well.
IRQ conflicts haven't been found.

If I connect the speakers back to the Nforce4 onboard card, the speakers work perfectly fine.

One more thing I noticed is when I unplug the cables and plug them back again, the speaker input is changed: for example, if I heard LEFT FRONT from REAR LEFT, when I unplug the cables and plug them back again, I hear LEFT FRONT from the CENTER speaker. Is there some kind of a sensor?

I read that people have problems when both x-fi and nforce 4 installed. But I wonder if anyone fixed those problems, or you just throw a $200 card in the garbage? Does somebody know how to fix this?

Creative forums don't give me any replies. HotHardware forums are down. I really hope that HotHardware could offer me some suggestions.

Thanks in advance,
Animy.

have you tired moveing the sound card to a different PCI slot?

that can sometimes help. also, are your settings synced with the control panel?

Wow. Thanks guys!

I didn't expect so many replies in just an hour or two!

I tried disabling the onboard card, but XP keeps bringing up the "New hardware found" question. Before the 8800 GTX, the onboard card didn't cause any problems. They both were enabled and were working fine. I'll try disabling it again though and uninstall its drivers.

It could be the power supply. I just remembered that I installed the card ignoring its requirements, hoping it would work on my 420Watt 12A power supply, while the manual says that it requires 450 Watt and 30 Ampers.

I'll also try switching it to a different PCI slot.

The speakers are connected to the back, so this isn't an issue with the front panel.

Anyway, I'll try applying your ideas and post the results when I'm done.

Thanks again.

Enter to your bios and disable the on board sound card don't just disable it from windows. Then download the latest drivers from creative for your sound card. Uninstall completely the old drivers and install the new ones.
Reboot your computer and change your speaker configuration to 5.1 in control panel. Give it a try it should work.

read the OP's post god dammit. everything was fine until he installed his new gfx card. nothing about speaker setup.

read my sig.

you mention you had problems however, they were in no relation to the OP's problem. he had already tried reinstalling the drivers. true in the end your way may solve it but there was no indication from his OP that it would.

now, i think i remember something about this. people have been having issues with soundcaards and 8800's. that is why i said to try switching the pci slots as although theres no reported IRQ conflict, AFAIK the 8800's can interefere in some way.

yes that is the vaguest post you will find but it is the best i can do at this time.

actually i may not be right about the x-fi/8800 part. it is this i was thinking about.

not sure how reliable this source is. http://forums.nvidia.com/lofiversi [...] 35609.html
