Audio Playback - Output specific talkgroups to multiple audio cards

[omgitsgela]

In our implementation, we are trying to route audio from specific talkgroups into individual virtual audio interfaces, which in our case links with Zello to make a more comprehensive and feature rich history stream than using a streaming service.

I would like to find a specific talkgroup within the system, and assign that talkgroup to use a specific audio card, and be able to do this with multiple talkgroups. The scanning setup to single card or mono L/R split doesn't work for what we want to do, and the streaming alias configuration poses technical challenges because our transmitting Zello app is expecting a microphone device, not an MP3 file. We are accomplishing the reverse audio routing using third party virtual audio cables to take the output of one application and force it to be a microphone input compatible with Zello.
