BlackMagic Ultrastudio Meltdown

MacBook Pro M1 Max, 64GB

Premiere Pro v22.1.2

Blackmagic Desktop Video 12.2.2 (currently back revving to 12.2.1)

As a note, this system was bullet proof until this issues presented itself last week, now all projects are affected. I have Premiere Pro’s audio settings configured as Blackmagic recommends in their user manual. 

When playing back video in a sequence, trimming, or toggling between program and source, audio in premiere will dropout. The software meters will stick in position, and the hardware meters on the UltraStudio and my Motu M4 aren’t bouncing. I can restore playback by toggling between timeline and source. Eventually this will happen more frequently until Premiere stops responding. From here if I unplug the UltraStudio’s Thunderbolt Cable, Premiere will come back to life. But plugging the Ultrastudio in doesn’t restore playback. It typically requires crashing Premiere, which will not quit, and re-booting the machine. From there the cycle starts over again. Very frustrating.

Has anyone seen this or a similar issue? I just spent 30 minutes with Blackmagic support and while the gentleman I talked to was very nice, he was not very helpful. 

I’m going to try to go back one driver version now and see if that helps. 

Thanks,
