This article was written for users that are having trouble with their PCI
Turtle Beach sound card either during installation or during general use. 
We recommend that you go through these steps before contacting Tech Support.

* UNINSTALL THE OLD SOUND CARD
  If you computer already has a sound card in it, you must uninstall the
  drivers and remove it before installing a new sound card. Please refer to 
  the computer or sound card manufacturer's documentation for proper uninstall
  information. 

    BUILT-ON SOUND CARD
    If your sound card is built into the motherboard, usually there is a 
    BIOS setting or jumper on the motherboard to disable the onboard sound. 
    Then you can uninstall the drivers. Please contact the computer or 
    motherboard manufacturer for help on this.

    BUILD-ON MODEM
    Some Modems also offer Audio features, acting as Sound Cards, creating
    conflicts.

* INSTALL THE SOUND CARD IN THE UNSHARED PCI SLOT  - Win 9x, Win ME
  There is usually only one PCI slot on a motherboard that is unshared 
  (does not share the same IRQ with other hardware or other PCI slots with 
  cards installed in them). Please refer to the computer or motherboard 
  manufacturer's documentation to find out which slot is the unshared PCI
  slot.

* NO OUTPUT FROM THE SOUND CARD
  Make sure that you are using self-powering speakers and they are turned on.
  Make sure your speakers are connected to the correct jack. Check your 
  manual to verify which jack to use. Please make sure that the output is not
  muted in your mixer. Test the output of the card with a pair of headphones.
  If the headphones work then the problem is with your speakers.

* IRQ SHARING - Win 9x, Win ME
  This is the number one cause of installation or general usage problems. 
  Avoid sharing Sound Card IRQs (Interrupt Requests) with other hardware. 
  This can cause a number of issues from computer locks and Blue Screening 
  to general audio problems. This is the first thing you should check. 
  You can avoid IRQ sharing issues by installing the sound card in the
  unshared PCI slot. Please see "Resolving IRQ Sharing" below.

* CHECKING FOR IRQ SHARING  - Win 9x, Win ME 
  IRQ sharing is when two or more devices are sharing the same Interrupt 
  Request. To check for IRQ sharing please open the Device Manager.  
  
  - In Win 9x, ME, right-click on My Computer, click on Properties, click on 
    the Device Manager tab.  Double-click on COMPUTER listed in the Device 
    Manager.  This will show all of the IRQs in use.  

* RESOLVING IRQ SHARING  - Win 9x, Win ME
  If you find that your sound card is on IRQ 9 or sharing an IRQ you will need
  to uninstall the card and move it to the unshared PCI slot. Usually, there
  is only one PCI slot on a motherboard that is unshared. 

  Note: 
      Every motherboard is designed differently so please contact the computer
      or motherboard manufacturer to find out which slot is unshared. If you 
      cannot get this information then you will need to try each PCI slot and 
      then check the Device Manager again and for IRQ sharing. 

  If your computer has an AGP (brown) slot then do not use PCI slot 1. 
  PCI slot 1 and the AGP slot always share. If you install the sound card in 
  PCI slot 1 then the sound card will always share the same IRQ as your video
  card. This is true in all Windows Operating Systems.
