Audio interface not working
Hi, I have Lexicon Lambda audio interface. When I connect it to my mac pro 2015 everything seem to be alright, but when I switch between input and output the window lags for a while. Then it seems to be ok and the USB device is selected, but while using Logic Pro X no sound is detected from the interface and no sound is playing. The same situation is with apple music, quicktime and even video on youtube. They all just stop at 0:00 and don't start. When I unplug the USB everything starts immediatly.
Please help with my problem, I'd appreciate it
thank you
