I have laid out a circuit that automatically switches the audio from 3 different amplifiers by just inserting 3.5 TRRS plugs but can't figure out how to turn off 5 volt power to the non-used amps. Any help would be appreciated.
thanks

 

Are you using all 4 connections of the 3.5 TRRS plugs?

 

Yes, two sets - spk = one set from external amp ( + - ) and the other from the internal amp that is chosen.
Yes, two sets - amp = one set from the globe amp (+ -) and the other from the aux input amp.

I'm wondering, if I take a picture of both sides of the simple 5 volt (maybe 10 components on the pc board), is it possible that someone might be able to tell me if I could solder leads to two of the solder joints and attach an AUX input, bypassing the Bluetooth signal? If I could do that, it would eliminate the AUX amp and all would be well.
Thanks
