I have a setup where I am monitoring for silence on an incoming stream on 3 different audio cards.
When I detect silence on the master I switch to the secondary, and if I detect silence there I switch to the last card.
The way I have it set up I load/unload the loopback module for each card depending on who's the active card.
This has the inconvenience that I need a 3-to-1 minijack cable to be able to maintain the stream.
Can I load the loopback module and point the output to a single card (independently of the input card)?
How can I route the audio from any input to a single output?
