I'm new at electronics and trying to do something for myself for USB and AUX
1) 3 inputs, 1 output:
I'll have 3 AUX inputs and want to switch to which input will redirect to output.
2) 1 Input, 2 outputs:
Most probably I can use same IC or something for this one too but wanted to give my scenario...
I already know how to use relays but most probably there is an IC for this kind of things... also; I have 3 computers and I'm also thinking about switching to HDMI signals with a single push button in this way (if possible of course).
