libao.conf






libao.conf − configuration for libao.




/etc/libao.conf

~/.libao


libao.conf and .libao are configuration files for libao, the
audio output library.  They specify various options to
libao, as described below.  libao.conf sets system‐wide
options, whereas ~/.libao sets user‐specific options.  When
an option is set in both places, the option in ~/.libao
takes precedence.


The file consists of comments and key‐value pairs.  Comments
are on separate lines that start with a # symbol.  The key‐
value pairs are of the form:
     key=value
where key contains no whitespace and no equal signs.  value
will be all of the text after the equal sign until (but not
including) the ending newline.  Beware of extra spaces at
the end of the line!  They will probably be interpreted as
part of the option value.

The following is a list of valid global option keys. Any
driver specific option may be used as well as those keys.

     default_driver
          The short name of the driver libao should use by
          default.  Valid values include (not all are
          available on every platform): pulse, oss, esd,
          arts, alsa, nas, irix, sun, roar and sndio.  Note
          that "sun" is used on many BSD systems as well as
          Solaris.

     debug (Value optional/ignored)
          Sets all the drivers as well as AO itself into
          debugging output mode.  Unlike passing the debug
          option to a driver, debug will also print
          debugging information from driver loading and
          testing.

     quiet (Value optional/ignored)
          Sets all the drivers as well as AO itself into
          silent mode.  Errors will return only error codes;
          neither ao nor the drivers will print any output
          whatsoever to stderr.

     verbose (Value optional/ignored)
          Sets all the drivers as well as AO itself into









                             ‐2‐


          verbose mode.




Here is an example libao.conf that forces the OSS driver to
be used by default:

    # This is a comment.
    default_driver=oss




libao.conf is missing a number of potentially useful
options.
