This problem occurs with all versions of Mimolive that I have used so far.
At the moment I use an Elgato Camlink4K interface to acquire a 1080 audio video signal, but I have also happened with others.
At almost constant time intervals of the order of 10/15 minutes, for about ten seconds the audio is damaged, after a few seconds it returns to normal.
Is there any way to solve the problem?
