Audio Research REF CD 9 SE
Description Of Issue
I just purchased a new Roon Nucleus+ to be used as Core, which replaces my Mac Mini which was used as a core. Of note is that I’ve been running the Mac Mini Core connected via USB successfully to my CD/DAC for several years. Nucleus is now connected to BT hub, Microsoft Surface Pro connected via WiFi network. I’ve updated Nucleus to latest firmware, formatted the SSD and loaded it with music per instructions. Roon remote from Surface Pro. All looks good, can play a song, but no output to my CD/DAC Help!
Of note is that my Audio Research REF CD 9 SE was recognized by Roon Core as displayed below on my Surface Pro running Roon Remote. I enabled and then renamed as show above.
Yes, I do. There is no stupid question Even tried a different USB cable, besides the brand new AudioQuest Coffee. Been at this so long, think I need another cuppa!
The only thing I can see that you apparently have not tried is using a different DAC. Do you have something else with USB input to try? That way you could ensure the Nucleus is operating properly… I am not a Nucleus user but since it is using ALSA, can you log into the root of the Nucleus OS and set the ALSAmixer output to max (or is there a UI page where you can do that)? Try setting the device volume control to max 100% in the Roon UI,
Took you advice and tried my travel Chord Mojo DAC and sound. However the goal was to ‘trade up’ and swap my Mac Mini Roon Core for the Nucleus+ and use my same Audio Research REF CD9 SE DAC via USB. Don’t believe I can log into Nucleus/Linux. Output is however to max 100. When my Audio Research REF CD9 was updated to SE, the USB no longer needed any drivers. I hope I can get this sorted out. Do want to stay with the USB.
OK so if Nucleus is working with another DAC the issue has to be in the REF CD9. Some incompatibility or strange internal setting, hard to tell. Perhaps it simply does not play nicely with Linux.
Hello and thanks. Became aware of this thread last night from 2018. Curious what news Roon Nucleus @support will provide. Have also contacted Audio Research Corporation.
The original CD9 was not Linux compatible. The SE is supposed to be Linux compatible and in the Absolute Sounds review Roon gets a specific mention. The only change between the original and the SE was the v3. Revision USB card. So this needs to be pursued. The SE is supposed to work.
