Topic: No audio signal in TM

Hello,
I've a Madiface xt connected via usb3 to my Mac Pro (with ADI 648 plus few ADI-8 via MADI) which is running on Sierra.
I use Pro tools 12.5 for recording (sometimes Logic X) but since few days when I open a new audio track, select the input channel, activate Input monitoring and record button there's no longer audio in the channel strip.
Even in Totalmix in the software playback raw there isn't any signal, it appears only into hardware inputs. And there is no way to make it work.
So I tried into Logic, almost the same result (no audio in software playback) but it shows up in the cs and even if I panpot for instance far left the audio remains centered.
Then I moved to the iMac that has an identical setup (Sierra etc.) and same issues.
Found on the net another guy who had the same problem and solved it reinstalling rme drivers and flash update so I did but the problem is still there.
I'm going crazy, any help would be appreciated
Thank you, Franco.
