NAME

       aoss - Wrapper script to facilitate use of the ALSA OSS compatibility library.

SYNOPSIS

       aoss osscommand [arguments]

DESCRIPTION

       aoss  is  a  simple wrapper script which facilitates the use of the ALSA OSS compatibility library. It just sets the appropriate LD_PRELOAD
       path and then runs the command.

       This is useful in cases where routing settings (which can be made in your .asoundrc file) need to be applied to commands that use  the  OSS
       API.

       Examples of asoundrc configuration:

       pcm.dsp0 {      type plug      slave.pcm "hw:0,0" }

       or

       pcm.dsp0 {      type plug      slave.pcm "dmix" }

       In  the	above  configuration  examples,  the pcm.dsp0 definition is used to wrap calls do /dev/dsp0. You can also wrap usage of /dev/dsp1,
       /dev/dsp2, etc. by defining pcm.dsp1, pcm.dsp2, etc..

       The PCM name to open can be given explicitly via ALSA_OSS_PCM_DEVICE environment variable, too.	This overrides the default dsp0, etc.

       Note on mmap: aoss mmap support might be buggy. Your results may vary when trying to use an application that uses mmap'ing  to  access  the
       OSS device files.

   Arguments
       osscommand
	      A command that uses the OSS API

       arguments
	      The appropriate arguments and options for the OSS command.
