The AES compatibility for Dante is rolling out slowly for different products. When we began implementing the AudioLan card we could only test with a few cards. During the last few weeks and also thanks to the reports from you guys, we have identified some SAP-related problem in some dynamic conditions. We have tried to fix these problems and hopefully, this also solves the issue you are discussing here.
Please update your AudioLan card with the latest release from the download section.
