Not the same options

[Impimperium]

So I have OBS to play Switch on my IMac, but I cant get the sound to work. And when I google, watch others videos on how to fix it and so. The same options they have, I havent. Is it the caption card I have or somthing else?
These are the only options I have, when others have so mutch more:
Anyone have any ideas? Thanks!
