Audio Hardware Conflicts
This section provides solutions to hardware conflicts. Hardware conflicts occur when two or
more peripheral devices contend for the same signal lines or channels. Conflicts between the
audio interface and another peripheral device may be because of the settings of the base I/O
addresses, interrupts, or DMA channels. The audio interface typically has the following settings:
■ Base I/O address 220H
■ OPL III I/O address 388-38Bh
■ Interrupt IRQ 5
■ 8-bit DMA Channel 1 and Channel 0 or 3
To resolve hardware conflicts:
1. Change the hardware settings of the audio card or the peripheral card in your system if the
peripheral card is using the audio interface setting.
2. If you are unsure of the settings of the peripheral cards, you can isolate the source of the
problem by temporarily removing all cards. After that, add the cards back one at a time
until the card that is causing the conflict is found.
