This is used in a flight simulator where audio is a pain! Some of the audio is coming from my network. ILS, and Radio Beacons Transmit Morse Code which I generate in the Linux pc. I pick my streams off using ALSA, and Jack which lets me put any stream into any audio card, that I choose. Then I have to run X-pairs of shielded wire from the PC to the Distribution Panel, and then daisy chained to other DP, a recorder, and an Instructors Console. Each Mic on the DP goes to 1 of eight radios. So all and all HELP!
