I’m unable to use Roon to play DSD or DFF tracks (file) onto usb storage .It couldn’t found the files then couldn’t play
I tested to play on HQP that works flawlessly. DSD and DFF files were converted from ISO by iso2dsd utility.Is this limited feature during trial? Please advise.

Roon supports DSF but not DFF. Convert the DFF files to DSF and Roon will see them.

OK. will do.

Thank you
