I just updated the firmware on my Studiolive RM32 AI and it’s caused problems. Using Mac OS Sierra, I updated the firmware. According to UC Surface, it’s been successfully updated. However, the mixer isn’t outputting any audio. The driver is set correctly to Presonus Firestudio in my Preferences. So two problems. The Presonus website isn’t recognizing my mixer, and there’s some problem with the driver and the OS and no audio gets output. Right now, I feel like if th9ngs on your computer are working, just leave it be.
