Description of Issue

I’m unable to provide all of the details supported by my DAC. As it is not a device with is natively recognised I have to select options from a list which end well before the maximum capability of PCM and DSD bitrates.

Is this not allowing the DAC to do its thing or is the Roon steaming/transport in the way?

If you are referring to DSD1024 or PCM1536, Roon doesn’t (yet) support those.

Yep, that’s it. You have max like you post here. I use the same DAC, if you want more, you have to instal HQPlayer.

BTW When Roon support > PCM768/DSD512? @danny

Yes, you will need to use HQPlayer and also check your ARES II firmware version.
They removed PCM1536 and DSD1024 in latest version becouse of issues with Apple devices.



  • Original firmware


  • Increase USB resync time to address USB out-of-sync issue

  • Supports PCM1536 / DSD1024


  • Fixed compatibility issue with macOS

  • PCM1536 / DSD1024 supports disabled

I guess I’ll need to look into this, not important as I do not have anything in that native format. Wonder how HQPlayer fits into the equation if Roon does not support the upper end of the spectrum. I’m trialing this along with JRiver which seems to play well with the native features of the DAC and up-sampling seems to work too. Same the library management isn’t up to par.

Yep thanks. I recall reading this online. My question was in relation to the native settings in roon which was answered by XXX, but thanks for your input.
