aria -- Sierra's Aria chipset audio device driver SYNOPSIS
aria0 at isa? port 0xPPP irq I aria0 at isa? port 0xPPP irq I flags 1 audio* at audiobus? DESCRIPTION
The aria driver provides support for Sierra's Aria chipset, which is the basis of such cards as the Prometheus Aria 16, the Genoa AudioBahn 16 Pro, and some Diamond Sonic Sounds (Rev A5 and Rev B2). The Sierra Aria chipset is full-duplex and is capable of 8- and 16- bit audio sample recording and playback at 7875 Hz, 11025 Hz, 15750 Hz, 22050 Hz, 31500 Hz, and 44100 Hz. Valid I/O addresses are 0x280, 0x290, 0x2A0, and 0x2B0. The IRQ may be set to 10, 11, or 12. The flags setting is necessary for the Prometheus Aria 16, as it needs to be specially configured at each cold boot by twiddling with the joystick port. SEE ALSO
audio(4), isa(4) HISTORY
The aria device driver appeared in NetBSD 1.4. BUGS
DMA is not yet supported. The flags option should not be necessary. It is necessary to configure the port and irq. BSD

sb -- SoundBlaster family (and compatible) audio device driver SYNOPSIS
sb0 at isa? port 0x220 irq 5 drq 1 drq2 5 sb1 at isa? port 0x240 irq 7 drq 1 flags 1 sb* at isapnp? sb* at pnpbios? index ? audio* at audiobus? midi* at sb? mpu* at sb? opl* at sb? DESCRIPTION
The sb driver provides support for the SoundBlaster, SoundBlaster Pro, SoundBlaster 16, Jazz 16, SoundBlaster AWE 32, SoundBlaster AWE 64, and hardware register-level compatible audio cards. The SoundBlaster series are half-duplex cards, capable of 8- and 16-bit audio sample recording and playback at rates up to 44.1kHz (depending on the particular model). The base I/O port address is usually jumper-selected to either 0x220 or 0x240 (newer cards may provide software configuration, but this driver does not directly support them--you must configure the card for its I/O addresses with other software). The SoundBlaster takes 16 I/O ports. For the SoundBlaster and SoundBlaster Pro, the IRQ and DRQ channels are jumper-selected. For the SoundBlaster 16, the IRQ and DRQ channels are set by this driver to the values specified in the config file. The IRQ must be selected from the set {5,7,9,10}. The configuration file must use 1 flags specification to enable the Jazz16 support. This is to avoid potential conflicts with other devices when probing the Jazz 16 because it requires use of extra I/O ports not in the base port range. With a SoundBlaster 16 card the device is full duplex, but it can only sensibly handle a precision of 8 bits. It does so by extending the output 8 bit samples to 16 bits and using the 8 bit DMA channel for input and the 16 bit channel for output. The joystick interface (if enabled by a jumper) is handled by the joy(4) driver, and the optional SCSI CD-ROM interface is handled by the aic(4) driver. SoundBlaster 16 cards have MPU401 emulation and can use the mpu attachment, older cards have a different way to generate MIDI and has a midi device attached directly to the sb. SEE ALSO
aic(4), audio(4), isa(4), isapnp(4), joy(4), midi(4), mpu(4), opl(4), pnpbios(4) HISTORY
The sb device driver appeared in NetBSD 1.0. BUGS
Non-SCSI CD-ROM interfaces are not supported. The MIDI interface on the SB hardware is braindead, and the driver needs to busy wait while writing MIDI data. This will consume a lot of system time. BSD
