Hi,
I’m reviving this thread because I’m having very similar problems with Wavelab 9 used with an RME HDSPe MADI card (PCIe).
After a while in a session, Wavelab will just stop producing sound, but all the meters and the transport are still working. Just no more sound…
I too been through every possible parameters, I’m usually pretty good at trouble shooting, but this one baffled me. Until I found this thread…
