NAME

     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 aria?


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.


BUGS

     DMA is not yet supported.

     The flags option should not be unnecessary.

     It is necessary to configure the port and irq.


SEE ALSO

     audio(4), isa(4).
