Connecting a DAC to Nativ Vita?

I believe this device is based on Android. I’m guessing you’re plugging the DAC into the Vita directly?

Right now, Android playback is limited to 16/48, but we are hoping to add full support for external DACs on Android in the future.

For now, I think the Vita will work as a control point, but if you want to use that DAC with Roon, you’ll need to plug it in elsewhere – to the Windows PC, to a Raspberry Pi, to a Roon Ready bridge (like the microRendu, for example), etc.
