I have a new DR-891 and was setting the setting in mu Win 11 computer. Using a USB-c to C cable at first i had both the USB speaker and USB mic in system. At some point my computer lost the USB Speaker. it shows up if I use a USB-C to USB A cable.
Not sure where I should be looking to get the C to C cable to work. Tried a couple different cables, re starts and trouble shooter in Win. no luck.
Do you still see the USB mic with USB C/C cable? If that’s the case the issue is not with the cable.
Check that you didn’t accidentally disable the playback device while trying to move the defaults.
