@miyagi1218, we have on here. It was broken for DSD only yesterday with B193, but with 194 it’s working for us.
Sometimes the CoreAudio driver in the NADAC can be finicky, and can get stuck. I’m worried that the problem you were experiencing yesterday might have put the driver or device into a confused state. Can you try:
Rebooting you Mac
Powering the NADAC off and on
It’s also possible that the NADAC lost track of the MAC–you may need to go to the front panel of the device and re-select the mac from the “SOURCES” menu. I think the name of your mac will turn red on the device panel when this happens.
We are testing using the latest drivers from MERGING’s website. If you last updated a long time ago, you may want to try upgrading, just so we’re all on the same page.
