As Sean told you today, while Innuos can play DSD files in native format, it is highly dependent on the DAC. See the link @yage gave you above.
I guess you already know that, but in Innuos Settings, go to Audio under System, then select one of the three options. If you get no sound under the last two options, DSD over PCM (DoP), or under Native DSD, it means your DAC is not compatible with Innuos to play DSD files, and will convert them to FLAC (first option, No DSD support must be checked). Sorry. You will still be able to play DSD files, but converted to FLAC.
