First which playout software do you use? Some playout software can stream and play with one card like RADIODJ. But if you don’t use radiodj or some other software that dont have that option,then you need 2 cards. 1 external for playout 1 internal for streaming,but internal in the properties you must set to stereo mix so that internal card can recognize sound from external card (i hope you understand). But there is a plenty tutorials on the youtube also i think that Mike on his channel did make tutorial how to make radio station,but im not sure. Can you explain about web station mixer?
This si the web station mixer so if i have 2 automation outpouts and then need to return that to the computer to stream - what is the way to and which sounds cards do you think ? You can switch the Web Station over to liive use (line and mics) or none stop vvia USB, allowing you to use such as for production or future Voice Tracking etc. So i think i need sound cards
This is from D&R web site about this mixer IT SAYS The USB/Line channels appear on a host PC as soundcard devices making the mixer ideal for playout systems. So clearly this mixer have sound card inside, you don’t need extra sound card. You can send output from that mixer into line in sound card that is in your computer (motherboard) and from that card you can stream sound/signal.
