Audio/Video Desync and Deterioration

[classicalmusicstreaming]

Hi all,
Trying to stream some concerts for a concert series - attached are the logs from our first concert where the video and audio became desynced and eventually pulled apart totally, with the audio then becoming garbled. We are running our audio system into an ATEM Television HD8 ISO, then to a Mac Mini. After this concert, we replaced the Mac Mini with a new 2024 model, and everything was fine for a week until last night, when the same issue happened again - and worse, with the video freezing and the audio becoming a series of pops. Unfortunately, I do not have the log for that stream. Any insights are much appreciated.

Sounds like the issue I have been running into as well. Both with SDI (Decklink) and NDI outputs over time.

MacOS Audio Encoding for SDI and NDI ouputs desyncs

I am surprised that there are no other posts about this on the forum. It's been happening for quite some time and I had originally thought it was the NDI issue but after the same identical issue happened to SDI, it is clearly on the encoder. Note that I have not included logs in this as it...

Is nobody else having these issues? Nobody using NDI or Decklink outputs on MacOS?

I can not speak to your exact issue, but any version newer than 31.0.4 will not provide any output on an Ultrastudio Monitor. I have tried it with two different Macs with two different UltraStudios. Downgrading to 31.0.4 appears to be stable.
