NAME

     emuxki -- Creative Labs SBLive! and PCI 512 audio device driver

SYNOPSIS

     emuxki* at pci? dev ? function ?
     audio*  at audiobus?

DESCRIPTION

     The emuxki device driver supports Creative Sound Blaster Live! cards as well as the Sound Blaster PCI 512.

     These Environmental Audio cards are based upon the programmable EMU10K1 digital-processing chip.

     Hardware features:
     o	 E-mu Systems, Inc. EMU10K1 music synthesis engine
     o	 64-voice hardware polyphony with E-mu's patented 8-point interpolation technology
     o	 Up to 1024-voice polyphony with multi-timbre capability
     o	 Support for real-time digital effects like reverb, chorus, flanger, pitch shifter, or distortion across any audio source
     o	 User-selectable settings are optimized for headphones, two or four speakers
     o	 Creative Multi Speaker Surround (CMSS) technology places any mono or stereo source in a 360 degree audio space
     o	 Processes sample rates from 5kHz to 48kHz
     o	 Hardware full duplex support enables simultaneous record and playback at 8 standard sample rates
     o	 Allows multiple audio sources playback on the same speaker system

HISTORY

     The emuxki device driver appeared in NetBSD 1.5.3.

AUTHORS

     The emuxki driver was written by Yannick Montulet <yannick.montulet@epitech.net>.

BUGS

     Currently, this driver does not support multiple source recording, MIDI nor the multi-voice capability.

NAME

     ess -- ESS Technology AudioDrive family audio device driver

SYNOPSIS

     ess*   at isapnp?
     ess*   at pnpbios? index ?
     ess*   at ofisa?
     audio* at audiobus?
     opl*   at ess?

DESCRIPTION

     The ess driver provides support for the ESS 1788, 1888, 1887, and 888 AudioDrive audio devices.

     The AudioDrive 1788 is a half-duplex device, while the 1888, 1887, and 888 are full-duplex. All are capable of 8- and 16-bit audio sample
     recording and playback at rates up to 44.1kHz.

     The AudioDrive takes 16 I/O ports. The I/O port range, IRQ, and DRQ channels are set by the driver to the values specified in the configura-
     tion file (or for isapnp, pnpbios, or ofisa, the values assigned from the firmware).  The I/O port base must be one of 0x220, 0x230, 0x240,
     0x250. The IRQ must be one of 5, 7, 9, 10 (or 15 on the 1887 only). The first DRQ channel must be selected from 0, 1, 3. The second DRQ chan-
     nel (used for playback by the full-duplex 1888/1887, ignored by the 1788) can additionally be set to 5. If both DRQ channels are used they
     must be different.

     The joystick interface (if enabled) is handled by the joy(4) driver.

HISTORY

     The ess device driver appeared in NetBSD 1.4.

BUGS

     The AudioDrive devices have a SoundBlaster compatibility mode, and may be detected by the SoundBlaster driver (see sb(4)) rather than the
     AudioDrive driver. The workaround is to remove the SoundBlaster driver from the kernel configuration.
