Hi, my friends and me use interfaces from steinberg. Jammr do not support this interfaces. Only one channel is avalaible.
It would be nice if jammr would support Steinberg drivers in the future.

Stay healthy.

Hi Uldarich,
Which model(s) do you have?

Please launch jammr, go to Help | Show log, and copy-paste the technical information that gets displayed onto the forum so I can look at the audio configuration. This will help me understand what is required to allow you to select other inputs on your interface.

Thanks!

Hi stefanha,
I use a Steinberg UR 44 Interface
I think i fixed it.
