Description Of Issue

Modi works great with my PC and Bose speakers, except for one thing. I can no longer control volume using volume control on the PC.

Is this normal/expected behavior? The Volume puck for the Bose speakers still works, but the output from the Modi is significantly louder than just connecting the Bose to the Intel NUC audio out directly.

Thoughts?

I believe the Modi is a fixed volume DAC with line level output on the RCA outputs. Your options are to use DSP volume control in Roon or connect the Modi to a preamp/ amp and control volume there.

You want to try and avoid this. This means you’re using the OS mixer which is poor for sound quality. Either use a pre-amp or enable Roon Volume control. Use one of the exclusive mode interfaces to your DAC. If you would like help with that post a screenshot of your Audio settings.

PERFECT! That’s exactly what I needed to know. I was able to set “Volume Control” to “DSP Volume” and was then able to adjust the output level to a more workable level. THANKS!
