Using Sound on Your PC Sound Board Settings Sound Board Settings The sound board in your HP Vectra PC supports Plug and Play. This means that when the board is installed, or reinstalled, the operating system is able to automatically configure various software settings to enable the computer to communicate with the board: • The IRQ (Interrupt Request) line is the signal line your device uses to notify your computer's central processor that it wants to send or receive data for processing. • The DMA (Direct Memory Access) channel is the signal line a device uses to transfer data directly to the computer's memory. The audio interface allows you to transfer data through the Low or the High DMA channel. • I/O addresses (or I/O address ranges) enable your computer's microprocessor to access various peripheral devices connected to your system when sending or receiving data. There are several such devices on your sound board. The following table gives the preferred settings for the sound board: Audio Interface: MPU-401 UART MIDI Interface: Joystick Interface: Stereo Music Synthesizer I/O Address Range: Joystick Connector: IRQ Line: Low DMA Channel: High DMA Channel: I/O Address Range: IRQ Line: I/O Address Range: I/O Address Range: 220H to 22FH Enabled IRQ 5 1 3 300H to 301H IRQ 9 200H to 207H 388H to 38BH The operating system may change these settings when a board is installed or reinstalled if one of the following occurs: • Another peripheral device uses the same I/O addresses, DMA channel, or interrupt setting as the sound board (known as a hardware conflict). • Another joystick/game connector is already in use in your system.
