Just had a similar issue when trying to record an AV patch, I was able to fix it by not drawing power from my laptop at all for Hypno by connecting hypno’s hdmi out to a capture card on a powered hub (that also is powering my audio interface) into my Mac.
I believe this issue stems from where the audio interface and hypno are powered. Ive had similar issue with my eurorack before when not even using Hypno and no output module so I think balanced line out may help here? (I haven’t recreated this yet but will keep experimenting)
