When I set mine up, I just set output driver to user defined and entered
alsa:device=hw=1.7 in settings.  I only want Smplayer to output to the
TV.  Everything else goes to the speakers hooked to the computer itself. 

The day may come when I use something other than Smplayer to watch TV
tho.  If, or when, that day comes I'll have to figure out how to get the
audio to work with it.  Right now, I'm still able to use the old gnome
player still.  It's going to die one day tho since it is no longer
maintained. 

I do find these audio topics interesting tho.  It seems it should be
easy to send sound to any place it can go but it isn't easy to do for
real.  It seems it is a problem for a lot of people doing what I think
is at least somewhat common.

Either way, glad you got it working.  It took me days to figure out mine
too.
