I may be misunderstanding what you're doing here but I suspect that
you need to use snd_soc_dapm_set_endpoint() to mark the outputs that are
not in use as disconnected. If you do that then then DAPM will not
power up the relevant output path.
You can do this at any point at run time - see sound/soc/pxa/tosa.c for
an example of this.
