NAME    [Toc]    [Back]

     aria - Aria 16 audio device driver

SYNOPSIS    [Toc]    [Back]

     aria0 at isa? port 0x280 irq 10 drq 0 flags 0x1

DESCRIPTION    [Toc]    [Back]

     The aria driver provides support for sound  cards  based  on
Sierra Semiconductor's
  Aria chipset.  Cards based on this chipset are capable of
     recording and playing 8- or 16-bit samples in mono or stereo
up to
     44.1KHz.   Some chipsets only play linear or ADCPM, but others will also
     play Mu-law and A-law sounds.  Three different mixer configurations are
     available.

     The  I/O  Port Base is selected from 0x280, 0x290, 0x2a0 and
0x2b0.  The
     selection method depends on the board.   The  Aria  takes  8
ports.

     The IRQ is selected from 10, 11, or 12.

     The  DRQ  line  is chosen from 5 or 6, this driver will work
with or without
     a DRQ.  If no DRQ is given, then the aria driver will simply
use Direct
     I/O.

     The  flags  currently  supported are 0x1, for the Prometheus
Aria 16/Aria
     16se.  This flag tells the driver to  initialize  the  card.
It is a weird
     and  undocumented  piece  of horribleness, but the card will
not respond until
 you twiddle with the joystick port.

BUGS    [Toc]    [Back]

     The driver has only been tested on a Prometheus Aria 16.

     No DMA support, yet, so don't bother setting a DRQ.

     The full-duplex features are  horribly  inconsistent  (i.e.,
unusable).

     The  card  sometimes drops out, and needs to be reset.  This
can be accomplished
 by opening and closing /dev/audio, e.g.,  ``echo  -n
>/dev/audio''

     The joystick and MIDI port interfaces are not supported.
