So, after some effort (and help from this group), I got Roon to work on my computer. Then, if you can believe it, the computer failed. It was under warranty, and they ended up giving me a new computer. So now I am back to square one.
Under audio settings, I enabled (Mytec) “Brooklyn DAC” with WASAPI, but it will still only play music through the computer speakers, not through the stereo system.
I looked in the user guide, but found nothing helpful. In Foobar or with the Tidal, it plays through the DAC. Just not in Roon.
What piece am I missing? @support
