Suppose you switch to the transformer, (and presumably you remember to put a pull-down resistor on the input of the IC so it is not floating), now the transformer is trying to drive the audio signal on pins 2 and 3, and the IC is trying to hold pins 2 and 3 at 0V. Which one wins?
Yes I know what you mean. It was just a rough idea.
The next question I suppose would be what to do with the secondaries/ ICout when there are not being used. Let them float or sort them to ground?
I believe a 100kOhm to ground would be a better idea than have them floating (?)
BTW, thanks for all your help guys.
