[zaacharia]

how can I use my audio interface as a input of audio, my interface have 8 input how can I use it all in obs i want to separate each input of interface to obs because if I don't separate the input of my interface the output of mic is compressed

don't know if this is the problem :
try [settings] - [audio] - [global audio devices]. If supported, it should be possible to activate each input individually. That will give you a control fader for each input in the Audio Mixer
