I just upgraded to MC for Mac: 31.0.83 from the previous 31 and I am immediately getting the message: "Playback could not be started on the output 'Core Audio" using the format 'DoP DSD64 (1x) 6ch'. This is affecting a lot of my albums but not all. A cursory look appears to be the SACD rips (DSD64). Do I need to go back to the previous version? If so I'll have to re-install it since I let the installer delete the old version of MC31. Thanks!
