SUMMARY

Your Sound Blaster card may continuously play a .WAV file. This may be caused by a hardware conflict with your computer. The Sound Blaster card is known to have compatibility problems with some fast 80486 systems and some system chip sets. Such a system may be unable to run these devices. This problem may also be caused by IRQ or DMA channel conflicts with another device.

If this is not a hardware problem but is a conflict, change the settings for either the sound card or the conflicting device. The recommended settings for the sound card are DMA1, IRQ7, and port 220h. Note: LPT1 often uses IRQ7, so it may be necessary to use another IRQ (interrupt request line). If you are unable to resolve any conflicts that occur, remove or disable one of the devices in the Registry database.

MORE INFORMATION

Registry Editor (REGEDT32) is provided for altering the Registry database. Note that you must be logged on with administrative permissions to alter certain Registry settings. You can alter hardware configuration settings under the Registry key: 

   HKEY_LOCAL_MACHINE->SYSTEM->ControlSet001->Services
You can disable or enable the Sound Blaster card by changing the entry for the sub-branch 

   Sndblst->Start
to: 

   0x4 or 0x1
