Yeah, the bigger issue unfortunately is that even if those modes helped your issue, there is no contract for their behavior so it could stop helping on a different device or architecture or after a minor or major OS update. That’s why OpenEars only uses the remoteIO audio unit and defaults to the standard audio mode even though other units and modes occasionally have better performance in various combinations depending on OS version and device.
The mode property was added after a lot of agitation for it, but I’m pretty likely to remove it in a future update since it has led to a lot of issues and support requests and I don’t have a great explanation for what it’s doing there if it causes problems without bringing positive results other than “people wanted it”; i.e. I made a design mistake.
