Brand new Envy 750-435st. Disabled on board audio in the bios, installed Soundblaster XFI card in Pcie slot. Tried to install drivers that were downloaded from creative's website. Driver installation came back with an error stating that it could not find any device in the system that used the drivers. Although card did show up in the device manager.
Removed the soundblaster XFI and installed a brand new Soundblaster Audigy FX in the same slot (there is only one PCIe slot). Was able to install drivers downloaded from creatives website succsessfully but sound is horrible. It is all scratchy and sounds horrible. NOTE: sound was the same horrible before drivers were installed as well.
Disabled on board audio
Tried 2 different creative labs sound balster cards in the PCIe slot.
Both cards show up in device manager but niether card functions correctly.
