A number of owners of X-Fi cards have come to experience what is known as a constant popping and crackling noise during use of the cards. Creative has attributed the case to be NVIDIA nForce motherboards, however many other users who do not use these motherboards continue to experience the sound issues. Creative has not provided a fix as of yet for this. Nevertheless there are unofficial recommendations how to solve these issues:
  • Move the sound card to another PCI expansion slot and reinstall the sound card's drivers
  • Replace native disk controller drivers with generic Windows ones
  • Update the motherboard's BIOS to the latest version (including "beta" versions)
  • Set the PCI Latency to 96 or greater
  • Use the X-Fi card only in "Audio Creation Mode" with "Bit-matched playback" option on
  • Overclock the PCI bus to 40 MHz instead of 33 MHz
  • Replace all of the capacitors on the card (At the expense of warranty)
  • Deactivate X-Fi "Crystalizer"
  • Deactivate unused devices in the motherboard's BIOS to free IRQ resources (RS-232 and Centronix ports, second Ethernet port, Parallel ATA controller, integrated audio)
  • Deactivate Plug and Play in the motherboard's BIOS
  • Update WiFi driver (HP Laptops)
  • Disable the sound card in Windows Device Manager before every shutdown, and enable it after every bootup
The newly revised EMU20K2 chipset used by the Titanium line of cards is said to solve the problem, further confirming the above PCI bus related fixes
