Ok so i finaly got my gtx 580(my wife let me go nuts) got it installed updated the drivers today and i lost my sound for speakers and headset.

Seems the new drivers if you express install did a HDMI audio driver that messed up my xfi card from sound blaster.

I uninstalled the niv one yet it still cant find my sound card/headset it finds a digital only that my earforce 11 headset works with useing the digital spdif box from my 360.

tried reinstalling my drivers (card number is SB0770) and it says it cant find the card.

tried running the Fixit program from MS and it cant find a card/head set either pluged in, took out the card and changed slots still nothing.

so after 3 hours of coming thru stuff on the net i am at a loss.


Anyone have any idea or clue what the problem is? did the card die somehow? lol

edit- the sdpif output on the back does not work on the card but does for the onboard spot but my speakers wont play thru the onboard either.

Go into the CMOS setup and clear or allow a reset of the NVRAM. Save upon exit.

didnt work under DM only high def audio device shows still and no sound from speakers.


Anyway to disable the sound card and make the onboard audio work atlest?

Each time you put in or take out a physical card do a NVRAM clear. I'm not entirely clear on what is going on but what I would probably do is remove the drivers for the sound card. Remove the sound card and disable on board sound in the CMOS. What I'm trying to do here is completely disable the sound apparatus. See if you can find a software tool to purge out the drivers completely.

Between all of this you want at bare minimum two full reboots of the OS and check that everything works the way it should before you put the sound card back in. I'm assuming that you don't want to rebuild the system from scratch unless you have to. I'm thinking either something is hooked up wrong, not seated correctly or the OS has driver confusion.

This is an IRQ conflict issue...move the card to another slot.

tried that with a bios reset and it didnt help.


will try and find a tool to clear the drivers.

Its either an IRQ issue, or your not supplying enough power...hence the reason the DEVICE is not showing in the DM.


Try the sound card in all the slots.


I hope you mean with the BIOS reset you removed and moved the card, cause the bios reset will not clear the IRQs...you can turn off devices within the BIOS that arent being used like onboard sound, IEEE 1394, and so on and see if it will free another accessable IRQ.

Yeah good point on disabling items in the CMOS. I always disable everything that I don't use for on board hardware and I allow in the CMOS setup for the OS to assign resources which most of the time is not a problem these days.

tried everything ya said nothing worked. but i did get my onboard working grabed the drivers for it and enabled it so got my earforce working with mic and 3 of my 5 speakers center and rear will figure out the 2 front ones tmw

Regarding the original post...

Did you go into the Windows Control Panel, Sound, Playback, and make sure the SB X-Fi speakers were the default device still?
