ESS488 Sound Card Cannot Be Configured for IRQ 10

Last reviewed: November 21, 1995
Article ID: Q139472

The information in this article applies to:

Microsoft Windows 95

SYMPTOMS

When you try to manually configure an ESS488 sound card in Device Manager, you may not be able to configure the card to use IRQ 10, even though you have configured the card itself to use IRQ 10.

CAUSE

Many ESS488 sound cards have been modified so that you can use IRQ 7, but not IRQ 10. The documentation included with the sound card may not reflect that this modification has been made.

RESOLUTION

To work around this behavior, configure the card to use IRQ 7 instead of IRQ 10. If IRQ 7 is not available, configure the card to use IRQ 3 or 5, or reconfigure other devices in your computer so that IRQ 7 is available. The card can also be configured for IRQ 2, but this is not recommended because IRQ 2 is used by the Peripheral Interrupt Controller (PIC).
