We’ve had this same ‘random missing audio’ issue since day one of using the H9K with the Logic Pro I/O plugin and Emote (5 years or more), although we are streaming the H9K audio over a Dante network. But in all these years nobody I’ve mentioned it to knows why or has a solution and I assumed it was either an H9K, Emote or Dante problem (or a combination of all) but I’ve recently been thinking that it’s more likely a Logic issue. A couple of years ago I found that if the audio to/from the H9K (via the I/O Plugin) goes missing placing a Logic Test Oscillator before the I/O and briefly activating it (be careful with your monitoring levels) can ‘nudge’ the I/O audio into action and the audio magically appears again,… akin to opening/triggering a noise gate – it doesn’t always work but often does, with our setup. I’ve also noted that some of our newer Logic projects never have this issue whilst older projects suffer quite badly with the audio going missing. I guess it’s down to some behind the scenes Logic routing shenanigans going on, who knows. Anyway we now have a handful of Logic templates that we know work with Emote… well 95% of the time (and using only one instance of it per project). Any older projects that are troublesome are moved to one of the newer working projects, which is both annoying and time consuming. Anyway that’s my take on it, maybe it will help.
