I have my DAC connected directly to my Nucleus and Roon recogniozes it even though it’s not a Roon tested DAC.
It’s a Marantz NA-11S1 which doesn’t need a driver for Mac OS but does need one for Windows.
How come Roon recognizes it correctly and works fine with it even without drivers?
And would that also be the case with a Marantz SA-10 (USB DAC + CD Player) that does need a driver for both Mac OS and Windows if I connect it directly to my Nucleus?
If it’s using usb audio ver1 then no drivers are required ybut your DAC will be limited to 96/24. If usb audio ver2 then its likely supported nativley in Linux as it’s been added to the the Linux kernel or it’s using genetic usb audio V2 support and you might find it’s does not support native DSD or other features.
No, but lInux doesn’t use drivers, its submitted as part of the kernel not a seperate driver, I believe. If its supported in the latest linux kernel then it would eventually be supported in the Nucleus.
If Linux is anything like Mac OS it does use drivers but they’re usually built-in or a generic driver If there’s no support at all built-in then you have to install a driver from the manufacturer in Mac OS.
My only problem is how to find out beforehand if a device will be supported or not by Roon OS or Linux. The NA-11S1 I have has been out for a long time but the SA-10 is a late 2017 model I believe which makes it less likely to be supported. Would be really troublesome buying an expensive DAC only to find out it doesn’t work with your setup.
Anyone from Roon here that can let us know how to find out if a device will be supported or not?
Just took a quick look at its specs, I suspect the standard Linux ALSA/UAC2 (USB audio class 2) drivers won’t support its fancier DSD modes. Roon keeps testing and certifying more DACs, but how easy it is to certify a new DAC depends on how much they “stretch” the envelope of UAC2, deliberately or through unwitting bugs. In your shoes, I’d not upgrade to the new DAC until Roon certifies it, to avoid frustration. Myself, I’m a pure PCM up-to 24/192 guy, which standard Linux setups support very well.
