BMD Ultrastudio 4K.
Audio begins to 'crack up' after several minutes until it's totally unusable. The 'crack up' is a total loss of audio for a few milliseconds at a time that becomes more and more frequent. It sounds like clicks or static or strobing. Here's a shot of what the audio waveform looks like:
Issue is resolved by restarting mimoLive. Then it's stable for a few minutes before the audio begins to crack again. Never had the issue before Sept. 16 and, as far as I can tell, nothing had changed. I confirmed that the audio is good/clean through the whole signal path up until mimoLive (monitored the audio directly off of the Ultrastudio and it was totally fine).
Updated mimoLive to latest beta version.
Updated to 10.13.6.
Updated all BMD software.
Still no joy. Precisely the same problem. I'm desperate to get this issue resolved before Sunday.
