Have a Nucleus connected via USB to a HiFiBerry DAC. Been working great. Changed over to the Marantz SA-11S3 SACD - DAC. Seems like any music source above 44.1K when played becomes distorted, somewhat randomly. The HiFiBerry is not available to do A-B tests, so I only have the Marantz.
Been troubleshooting, but having difficulty identifying the common denominator.
Notice the Core believes the Marantz has two virtual USB Audio inputs (because only one USB cable is connected, and both “devices” will play music through.) Can’t find any info about this from …anywhere. Do you know the difference between the inputs?
I am 100% certain that one input has less of a problem with distortion than the other. I am also positive that the distortion does not seem to appear when Device Setup’s Max Sample Rate (PCM) is lowered to “Up to 48kHz” from “Up to 192kHz”
Ive tinkered with buffer sizes and resync delay to no avail.
Generally for a USB DAC to be compatible with Linux such as Nucleus, it has to support driverless operation on Mac OS. Your device requires a driver on Mac, meaning its USB is likely not compatible with Linux (and therefore Nucleus) - since you posted this problem it’s an evidence to support this theory.
Your best way to go forward would to be use a coaxial output, via a network endpoint (from our company or others).
The Marantz SA-11S3 is a USB Audio Class V2.0 device. However, if I was to hook my computer to it - yes, it would require a driver.
If the Marantz DAC is performing fine with the Nucleus, with exception of distortion that seems limited to playback rate > 44.1/48k, do you still believe it is a USB compliance issue?
