I had to go back to WL10 to learn some more about WL 10 (I am using WL 9.5.5 until the patch comes out) and so I was playing back in WL10 with my RME card and then switched to WL 9.5.5 and there was no sound from WL 9.5.5. I went back to WL10 and it too would not playback through my RME 9632 card. This is the third or forth time this has happened. This NEVER happened when I was using WL 9.5.5 I have the “release driver in background” checked on both 10 and 9.5.5. Weird to say the least. I reinstalled the RME driver and everything is back to “normal” for the time being. I checked all my drivers for Windows 10 and updated the ones that needed updating (about 5 drivers).
