I'm new on this list, worked for few decades under Linux, but just starting with audio. In short, I cannot play any sound on my Presonus Studio 1810c usb interface. I spent quite some time searching for related info. Here's how far I got so far.
I'm running on a laptop:
OS: Ubuntu Studio 19.04
Kernel: 5.0.0-16-lowlatency
Processor: i5-2520M @ 2.5GHz
Memory: 8 GB
Graphics: Nvidia 4200M
The manual states that no driver is necessary on Mac, so should be usb class compliant. The device is recognized (S1810c) and snd_usb_audio module is loaded:
