Hmmm … WYCA on our system the RME (AIO) will allow WL to play again after a short while. No refresh is required. Also, on the other thread, I made the observation that I had reason to suspect that this issue is more to do with the RME card/driver. The reason is that in my system, the RME send AES to Mytek converters. I notice that the lights on the Mytek are lit, but frozen, as though it was receiving AES from the RME but WL appeared to be ‘hanging’. This might not be immediately obvious unless you are sending AES to an external converter. I think in your systems you also send AES as well? Good luck.
