audio/Video Synchronisation problems

What is the best solution for audio acquisition, without having Audio/Video Synchronisation problems?
Is there a console, cards or other that works really well?
I work on conferences where the sound is sent back to me via a sound engineer.

My configuration is as follows:

  • Mac pro 2020 / Mac osc catalina
    -3.5 GHZ intel 8 hearts
    -96 GO
  • AMD radeon Pro W5700 16 GO
  • A SONNET Box, ECHO EXPRES SE III
  • Decklink 8K Pro
  • Decklink Quard HDMI Recorder
  • Decklink mini monitor 4K

Thank you in advance for your help
