ZAUDIO(4)            OpenBSD Programmer's Manual (Zaurus)            ZAUDIO(4)

NAME
     zaudio - Zaurus audio device

SYNOPSIS
     zaudio0 at pxaip?
     audio* at zaudio?

DESCRIPTION
     The zaudio driver interfaces the sound hardware found on the Zaurus with
     the audio(4) framework.  Sound support on the Zaurus is provided by the
     Inter-IC Sound (I2S) Controller which is used to transfer samples to a
     Wolfson Microelectronics WM8750 audio codec.  The WM8750 is controlled
     via the PXA2x0 I2C Controller.

     The hardware is capable of using both the internal speaker and headphone
     socket for the playback of 8- and 16-bit audio samples at rates ranging
     from 8kHz to 48kHz.

SEE ALSO
     audio(4), intro(4), pxaip(4)

HISTORY
     The zaudio device driver first appeared in OpenBSD 3.8.

AUTHORS
     The zaudio driver was written by Christopher Pascoe <pascoe@openbsd.org>.

CAVEATS
     Recording is unimplemented in the zaudio driver.

     The zaudio driver only supports the hardware found on the Zaurus C3000,
     C3100, and C3200, though support for the C860 is planned for the future.
