I have found a way to run where Roon doesn’t lose contact. I configure Roon to have a maximum sample rate of 48kHz and maximum bits per sample of 16.
- Turn on the DAC first and then the USBridge. I’m not sure this makes a difference but it seems to.
- Configure Roon as shown below.
- I seem to get better luck when I tell it this is an EX-8. There is no selection for the Codex or the QB-9. I’m not sure this really makes a difference, though.
- I don’t think the Buffer Size or the Resync Delay matter, but they seem like they would be more robust.
Using these settings, I was able to play a 96kHz, 24bit album from my NAS several times through. Since about 95% of my library is 44kHz, I think I can live with this while I look for a more lasting solution.
