[Vorbis] ogg123 volume?

[Barton Hodges]

Hi,

I need to adjust the output volume from ogg123 the same way that
mpg123 has the "-f n  change scalefactor [32768]" option.  I need to
do this within ogg123, instead of alternatives that involve pipes,
such as piping the output to sox.

I do not believe that this is currently possible in ogg123, and I'm
looking for some suggestions as to how it can be accomplished by
modifying the ogg123 source.

Any help would be appreciated.
