Re: Mac USB driver for macOS 11 & Apple Silicon hardware
Emmm...Apple Silicon doesn't have NVRAM reset big_smile
I guess what helped was just restarting the operative system?
But here you are comparing apples with oranges. The Arturia is a 4-channel audio interface, where a total of only (!) 8 input and output channels are permanently transferred via USB2. The UFX III is a 94 channel interface where 188 input and output channels have to be permanently transferred via USB3.
This is a much higher audio bandwidth that has to be permanently transferred via USB. It doesn't matter if the inputs or outputs are in use, everything is always transferred by the driver.
So if there is a problem somewhere in the Apple operating system that interferes with real-time audio processing, it is no surprise that the likelihood of audio problems is higher with an interface that has more channels (in this case, many more channels) as so much more audio data has to be transferred / processed in time.
Interesting, I didn't know everything is always transferred by the driver.
