I appreciate any help .
I have the Asus P8Z77-V Deluxe with i7+16GB ram.....and 680GTX with creative ZXR.
All was perfect , until I got a new 680 for sli, and had to change the place of the creative zxr from pciexp1_3 to PCIex1 blue1_1 (the other remaining PCIE1 blue remaing is between the sli cards)
SO now @ random power on just befor the UEFI or the boot logo appears an irritating hiss like sound comes from the speakers connected to the ZXR, and when windows load, I can only see (in the device manager)sound blaster audio controller +sound blaster zxr dbpro , what is missing is the "sound blaster zxr" that used to show when there is no hiss .
I changed the place of the ZXR to the PCIe1_3 between the sli cards, and after many attempts no hiss came, even tried the PCIe16_3 (the black one)and the his came back .
The only fix was to place the card between the sli card which gave me 7 degrees increase in temp in the GPU1.
I removed the 2nd 680gtx card and kept one and tested to see if the problem was from the sli, and the problem stayed, so I concluded that my ZXR only liked the PCIE1_3! any logic?

This his is not"Sound/os/bit-rate related" as I mentioned the hiss starts just before the boot screen, and I have a corsair AX850 .
The problem is strange, when the Hiss/static sound starts the Sound blaster ZXR is not in the devise manager as with the above picture only Audio controller and dbpro are there.
So I can not chose the card as a default player as its not being "fully detected" hence no sound will be played except the hiss/static like sound.
The card will work without the hiss sound sometimes and sometimes not! in the PCIEX_1.
The only position where this issue is absent is between the GPU cards in PCIEX_3...I know this makes no sense but I tried every imaginable scenario, and yesterday updated to bios 2003, thinking maybe ....unfortunately, nope!
I left the PC off for 6 hours and then turned it on and the hiss is still there , so the thermal issue is not the case.
The only other fix , if there is hiss, is to turn it off and on again and the hiss is gone??!!
