Merging Hapi spitting on AD into Wavelab

Hello,
Recently my Hapi converter via Ravenna started to spit on the AD side into Wavelab. This is not happening when going into Pyramix. I also noticed that whne wavelab is open, it is reading the correct ASIO driver (Merging Ravenna), but all values are 0. This was not the case just a little while ago, bu it just started to happen. I am checking if an update occurred but I have them on pause. I’m running a Windows 10 machine. Anyone using the merging Hapi converters with Wavelab experiencing this problem?
Thanks.

Hello,
Here is a visual of the dropout when recording 1kHz.
Any help here?

Figured it out. Buffer size.
I had to do a complete clean install of Merging drivers, including the MergingRavennaASIO. This defaults to 64 sample buffer. Increasing to 128 or higher stopped dropouts. Forgot that I had to do this years ago when I set this system up originally.
