Just done a new install of WL8.5.2 on a Win7/64bit machine with an RME HDSPe AIO.
50% of the time, when I load WL and load any file, WL just hangs when I press Play. Sometimes I can quickly press Stop and regain control. If I go and change the outputs, then it will work. Doesn’t matter what I change it to - just the act of changing saves it. But then the same issue will happen after some restart in the future, so it’s not the actual outputs that are causing the problem.
At other times, everything works fine when I load it without me doing anything.
Don’t have any issues with Sound Forge, Cubase or anything else. Just Wavelab.
