Comment(by chhamilton at hotmail.com):

 I've attached a patch that adds software preamp software to
 AudioOutput/AudioOutputBase.  The approach taken was to inplace modify all
 samples fed to AudioOutputBase::AddSamples.  There is also some early
 clipping monitoring stuff in place, which could eventually be used to
 implement an automatic gain control if so desired.

 The patch is relative to the mythtv/libs/libmyth directory of revision
 16313, and can be found
 [http://svn.mythtv.org/trac/attachment/ticket/4804/preamp-r16313.patch
 here].
