So that they are already with the knowledge, I have the latest drivers installed, the firmware of the desk is up to date, I use a MacBook Pro (13 inches, mid 2012) with ox el capitan and my desk is a Presonus StudioLive 16.0.2. It turns out that for no apparent reason, and I inform that my desk only works in the studio, every time I turn the firwire cable on or off the table stops playing sound, that is, the indicators show the input signal and the output signal, however, there is no signal in any of the outputs. From what I've read, a lot of people have the same problem, which is not good. I hope they give me the resolution to the problem because otherwise the table is of no use if there is no sound. Thank you.
