Roon/Nucleus doesn't recognize DAC after latest update

[connor]

Hi @Joe_Spivey,

Please accept our apologies for the lapse. We’ve confirmed you’re encountering an issue with external USB devices on Build 1148.

We have a high-priority ticket with senior developers to resolve this issue, and there should be improvements if you update to the latest build of Roon on your Core and all devices in the meantime. Roon 2.0.5 and ARC 1.0.5 are live!

2.) I ordered a HDMI to USB adapter to try in one of HDMI ports. Not really sure if that’s something that would work but thought I’d give it a shot. Does anyone have experience with an adapter of this kind?

This workaround may work; the issue is with the mounting process for USB drives in RoonOS, so any other output shouldn’t manifest this issue. The team doesn’t have direct experience with these digital converters, but you could peruse the Audio Gear Talk section.

3.) The DAC manufacturer doesn’t know what the issue is and hasn’t heard from other Roon client’s using this specific DAC of any issues. He offered to replace the USB input circuit board if I ship it back to them for a fee. Wonder if I should give that a shot?

I recommend waiting for a status update from the Roon team if you still experience this issue on the latest build rather than taking any hardware replacement steps. Proper unmounting commands can resolve the issue, so let us know if you still experience the problem, and the team will proceed from there.

We’ll be watching for your response.
