FT-891 with Digirig DR891 and VARA HF

1

I’m trying to configure VARA HF with my Digirig DR891 and the FT-891. In Vara HF version 4.9.0, there are a couple settings that I’m not sure how to set with the DR891.

  1. Should I select “USB” or “USB Digital” ?

  2. Should the box “Use radio internal soundcard” be ticked ?

Thanks
