Yorkville mixer with audio interface

[P.J. Thankee]

I have Yorkville 16 channel mixer with USB audio interface.
I send all sounds to my mixer, like Korg Pa 1000, Handsonic and my wife's mic
From mixer i send all those sounds to mac book air.
In OBS i have set USB Codec , also monitor and output.
i send this sounds from obs to zoom, microphone as USB codec
any suggestions for any other way to set up?
tried VB cables, NDI . not happy with the output
but mixer audio interface has given me 70% satisfaction
My wife and I do live stream for shut in. temples and meet in zoom
I am 68 years old
