I use my computer as a DAW (digital audio workstation) and all other tasks. After a month of having to unplug my speakers from the audio interface to the computer I decided to build a passive balanced left/right A/B switch. (These switches are non existent online). The switch works well and saves me the trouble of having to reroute outputs manually. However there is a noticeable 'pop' when I switch input from computer to external audio card and vice-versa.
I have been unable to find any schematic or advice on how to eliminate this popping sound. I have read that a 100k resistor can be used but I can find no information on where in the circuit to put it.
