EAP(4)                  NetBSD Kernel Interfaces Manual                 EAP(4)


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 programs
     to use the "same" audio device simultaneously.


SEE ALSO

     ac97(4), audio(4), joy(4), midi(4), pci(4)


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.
