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 | ||
■ | Interrupt | IRQ 5 |
■ | 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.
