Halloween Sound Control Board Revisited
After making this video I realized I am probably cutting a corner that I don't want to cut.
I want to switch input signals going into a headphone jack between the propeller chip and an external Zune mp3 player. I
was hoping to get away with just a relay in between the zune in the headphone jack, but when the zune is connected to the jack it will also be connected to the propeller chip. So now I am thinking I will need relays
in between both propeller chip and the zune. Or is there a simpler way of doing this?

So I should put left audio channel pin of Propeller to normally open pin of relay and left pin from zune's headphone jack going to same relay's normally closed pin and then
the relay's common pin going to output headphone jack.
They have been sending groups through at 10 minute intervals with each group only spending about 2 minutes
with us so the system plays way more music then monster sounds.
