+.Sh DESCRIPTION
+The
+.Nm
+driver interfaces the sound hardware found on the Zaurus with the
+.Xr 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.
+.Pp
+The hardware is capable of playback of 8- and 16-bit audio samples at rates
+ranging from 8kHz to 48kHz.
+.Sh SEE ALSO
+.Xr audio 4 ,
+.Xr intro 4 ,
+.Xr pxaip 4
+.Sh HISTORY
+The
+.Nm
+device driver first appeared in
+.Ox 3.8 .
+.Sh AUTHORS
+The
+.Nm
+driver was written by
+.An Christopher Pascoe Aq pascoe@openbsd.org .
+.Sh CAVEATS
+Recording and volume control is unimplemented in the
+.Nm
+driver.
+.Pp
+Only the internal speaker is used during playback;
+the headphone socket is currently unsupported.
+.Pp
+The
+.Nm
+driver only supports the hardware found on the Zaurus C3000, though support
+for the C860 is planned for the future.
