I have a pair of Alesis Active Monitors which have a USB input and it's a pain connecting devices to it so I felt using a Rasberry Pi with bluetooth and audio ins to allow for multiple connections maybe a way around it.
My plan would be to have a Raspberry Pi Zero W or something in future but i'm just testing with a Raspberry Pi B+ which was laying around. I want to plug the speakers into it via USB and use as the only audio out however then have a bluetooth in mode and analog audio in so may need a second USB sound card with inputs and was wondering if this would work and how I could switch the inputs (e.g. use some kind of switch on GPIO or something that will run a script to change the inputs)
Before I buy some of these bits can anyone tell me if this will work?
