Optimizing your system for better sound performance

----------------------------------------------------------------------

Our Advice
Whenever I play back audio files, I get random drop outs, repeating sounds or constant distortion (hissing/crackling sound).All these symptoms (and any other degradation of sound quality for that matter) can mostly be traced back to system / BIOS settings that prevent your audio sub-system from functioning properly. In other words, if your system is optimised ("tweaked") for a specific task, the result might be that the extra bit of 3D power or data transfer speed to the drives uses up so much of the systems resources, that there is simply not enough left for your sound card to do its job as it should. Sometimes even the factory settings of certain PCs / Motherboards can cause symptoms as described above.

The following guide is separated into the following main sections:

General troubleshooting considerations
Toggle the DMA access options to the harddrive
Reduce the the Hardware Acceleration of the graphics card
Change the IRQ for SB 16 Emulation / Legacy Device
Disable ACPI configurations in Windows 2000/XP
BIOS settings

1. General Troubleshooting steps
Ensure your Sound Blaster card is installed in a PCI slot as far away as possible from components such as graphics card, CPU and hard drives.
Ensure that the PCI slot doesn't share resources with other devices in your PC (mainly graphics card, drive interfaces, etc...)
Remove all unnecessary hardware. Every device installed in your system uses some of the available resources, even if you do not actively use it.
Tidy up all cables inside your computer as electrical interference may be caused otherwise.
Ensure that audio drivers are up to date.
Download and install the latest chipset drivers and BIOS update. The major chipset manufactures are: VIA/ETEQ, AMD, Intel, SIS. Ali Note: If you have a motherboard with a hybrid chipset consisting of AMD Northbridge and VIA Southbridge, ensure you download the latest driver package from your motherboard manufacturer.
2. Toggle the DMA access for your drives:
Windows 98SE/ME:

Select Start - Settings - Control Panel then double-click System
Select Device Manager
Double-click the Generic IDE Disc Type (xx) entry found under Disc Drives and click Settings
Uncheck box next to the DMA (Direct Memory Access), then click on OK
Windows 2000/XP:

Click on Start - (Settings) - Control Panel - System - Hardware - Device Manager.
Click on View and select Devices by connection. This allows you check which IDE controller the Hard drive(s) is (are) connected to (See Image below)

Locate your Hard drive(s) and double click it (them) to open its (their) property-sheet(s).
This allows you to find which drive is connected as Device 0 or Device 1 (Location, see Image below).


Right-click on the IDE Channel to which the drive is connected (in our example "Primary IDE Channel"), select Properties and Advanced Settings.
Click on the Transfer Mode drop-down menu shown under the device number that represents the location of your drive. Select PIO Only. (See Image below)
