I haven't really seen this mentioned anywhere else which makes me think it's not possible and I'll have to use OBS... I would like to stream sessions of music through ReLive but as far as I can tell there's no way to set which sound card it captures its audio from and it always uses the one that the system is set to. This is a problem because my instruments come through an audio interface and if I set my main Windows output to that card, it overrides everything coming through the inputs.
Is there any way at all to tell ReLive to capture audio from a second sound card?
