NAME

     bba -- IOASIC Baseboard Audio device driver

SYNOPSIS

     bba0   at ioasic? offset ?
     audio* at audiobus?

DESCRIPTION

     The bba driver provides support for the IOASIC baseboard audio found on DEC 3000/300, 3000/500 (NetBSD/alpha) and DEC Personal DECstation
     (NetBSD/pmax) systems.  The baseboard audio driver is based on the AMD 79c30 ISDN and audio interface.  The interface is only capable of
     playing and recording 8kHz mu-law audio.

SEE ALSO

     audio(4), ioasic(4)

HISTORY

     The bba device driver appeared in NetBSD 1.5.  The name for the driver was adopted from the same driver in ULTRIX.

NAME

     eap -- AudioPCI audio device driver

SYNOPSIS

     eap*   at pci? dev ? function ?
     audio* at audiobus?
     joy*   at eap?
     midi*  at eap?
     options EAP_USE_BOTH_DACS

DESCRIPTION

     The eap driver provides support for the Ensoniq AudioPCI and Creative Labs SoundBlaster PCI series of audio cards.  All models based on the
     ES1370, ES1371, and ES1373 chips are supported.

     By specifying:

	   options EAP_USE_BOTH_DACS

     a second audio device is attached.  You can use it simply by directing audio output to it.  This way it is possible for two different pro-
     grams to use the "same" audio device simultaneously.

HISTORY

     The eap device driver appeared in NetBSD 1.4.

CAVEATS

     The joystick port hardware works by emulating a legacy isa(4) joystick port, bypassing the pci(4) bus method for address allocation.  This is
     unlikely to work on PCI busses other than the primary one.  There is also a possibility for conflicts with real ISA devices because the PCI
     bus is probed before ISA.	Use with caution.
