Dante should be fine without DHCP as well. It's perfectly happy dealing with APIPA addresses. We use static because it makes things easier to find on our network. One of my volunteers is a genius at scripting and we've automated a number of things through their respective APIs, so we just have a list of all our devices to reference and since it's just the two of us doing any of the network nitty gritty stuff, it doesn't matter when gear is swapped because we're the ones doing it. BUt Mike's point is very valid in a setup where the end user is not savvy with IP networks.
We did have a wacky instance using Magewell HDMI to NDI converters where they would not detect NDI sources unless they had DHCP turned off. That's a bug though, not a feature LOL. They just like static IPs better.
I think your best bet is what Mike's advice was to me. Narrow it down and eliminate things. I would definitely check that switch config since it seems like it's the smoking gun right now, but the VLAN setup you've got could also contribute. The weird part is still that you're having audio signal drop outs with no clock errors showing up in controller. THat points to gear on the transmit or receive side being at fault (like in my problem).
