Hello @Ke_Zhang,
I had the tech team take a look at your logs again with the report of the Hugo, and unfortunately they were not able to find anything conclusive on what could be causing this behavior. They recommended reaching out to the manufacturer to see if there is any guidance they may be able to give on why things would be working with the Hugo connected to the Mac but not the Audiophilleo 1.
You can find more information about known issues with the Audiophilleo products in this thread. We still have not received any devices to test from the company.
I do have a few more troubleshooting steps we can attempt to potentially isolate the issue. Do you have the Audiophilleo 1 updated to the latest firmware? When you open the “Audio MIDI Setup” application on your Mac, what do you see happening when you try and change sample rates when playing to the Audiophilleo 1?
