After upgrading to 8.5.2 I’ve got a bug of my ASIO stream being doubled to the windows speaker device (same physical port defined as windows speaker in windows control panel)
In WL ofcourse I’ve selected the ASIO RME driver, nothing WDM related is enabled in WL.
MUTING windows speaker tray icon solves the problem, going back to previous version of Wavelab as well
8.5.2 is also the only ASIO program “leaking” to the same port under WDM, don’t have this problem in i.e. cubase.
