Your issue made me get up off my butt and install MC20. *
I have a Schiit "Uberfrost" DAC (best current audio value out there) - my settings are at:
http://yabb.JRiver.com/interact/index.php?topic=86075.0I installed MC20 just now as if it were an MC19 update, but accepting the default new MC20 folder.
Everything is working fine, my Playing Now even had the same audio files.
I am using "ASIO for C-Media USB Device [ASIO]" which is the Schiit 1.03 drivers. I did not uninstall or reinstall the Schiit drivers.
Everything is working fine, thanks to JRiver peeps.
