[mythtv] [PATCH] Big audio update redux

[David George]

This patch adds my ALSA and volume control changes to Ed Wildgoose's big 
audio update.  I haven't finished the volume control changes so volume 
control is disabled in this patch (including OSS!).  Ed said that he 
could take a look at it Sunday or Monday, but here it is in case someone 
wants to look at it.  Basically tv_play can't access the volume control 
because it is part of the AudioOutput class and NuppleVideoPlayer has 
that as a private.  I know I can fix it, but don't have time right now 
to make sure that I do it the correct C++ way :-) .

This is against CVS as of 11am today (US EDT).  It includes all of Ed's 
changes and will also create the new files that Ed created.  Make sure 
you use my small OSS define patch sent to the list a few days ago before 
applying this.

There is still one audio issue, but it affects OSS and ALSA.  When 
playing a recording and the screen fades to black for the commercial 
audio will drop out and you will get an A/V sync stretching frame 
message in the logs.  This seems to have started around .16 and doesn't 
seem to be related to the audio code.

Have fun,
David
