The last two times out with vMix, we have had an issue where the Master Audio suddenly mutes. I have been able to catch it both times fairly quickly, but was unaware of what the cause was. Looking back at our program recording it seems to have been caused both times by switching cameras (which I do NOT have set up as triggers). The first time it looked like a rapid double switch (i.e my TD fat fingered one of our buttons and instantly switched to the correct camera next to said button) and it only muted the master audio. The second time however, it was just a simple switch from a low angle to a high angle and it not only muted my master audio, but it also cleared my active overlay channels.

I have checked my triggers and that is all squared away so I am really at a loss. Has anyone ever experienced anything similar and have any solutions, or do I simply need to email support and speak with them?

Cheers.
