OK, here it is step-by-step.

There’s an audio settings button in the bottom right corner of RB. I clicked that and I see audio preferences.

In audio preferences, I have select ASIO selected. On the same page if I click on drivers, I see Focusrite ASIO inputs three and four, which are correct. For output ports I can only pick outputs on the Focusrite. There’s no mention of a headset on that page.

Then I close that page.

I go back to the audio settings button and this time I look at playback devices. I select the headset which shows up fine on the little Windows menu that comes. There’s a checkmark next that I selected that for playback.

When I go to play my work, it still comes out of the Focusrite speakers. It doesn’t come out of the headphones.

I know that’s a lot of text to wade through, but I wanted to be complete in the response.

Thanks.
