I recently upgraded to Audirvana V3.5 on a Mac mini (Carolina) USB-connected to a PS Audio DirectStream DAC running Windom. I can play PCM tracks with no problem. I can also play DSD tracks as well but the software is using DoP or it’s converting to PCM. The DAC indicates that it is locked to a PCM stream. Also, the software settings.indicate that DSD is not supported by the DAC but DoP is an option. I had the exact same experience with the Snowmass release of the DAC, the one prior to Windom. I haven’t had any insight on what’s happening over at the Audirvana forums. Has anybody had this problem. I’d like to run native DSD as I did before. Thanks! ---

Raw DSD is only supported via I2S if I remember correctly. Since you’re using USB you’ll have to use DoP, which is technically the same thing. ---

Hi seegs108, You’re right about I2S but native DSD also works over USB. I’ve attached an excerpt from the DS manual indicating as much. ![image](https://us1.discourse-cdn.com/flex015/uploads/psaudio/original/3X/2/7/274cdb1cccb2ddde639cffd71427ba73773bf31b.png) It worked with the previous version of Audirvana. ---

I bought my DS with Snowmass and I’ve never been able to send native DSD from Audirvana via USB. Not that it really matters, in a different thread Ted stated that the DS uses DoP internally, so in this case DoP is the “native” format. I use Audirvana 3.2 because I don’t like how 3.5 sounds. ---

Thanks, IanB52. Can you tell me if your DAC indicates its locked on PCM or DSD? ---

It says Input: DOP, Rate: DSD64 ---

I reinstalled Audirvana and re-flashed the DAC tonight and got your results! Yay! Still don’t know why I don’t have the option to go native DSD though. Maybe I’ll try 3.2 again too based on your comments. Cheers! ---

I know some people really like 3.5 but I felt like it took away a lot of the dynamics and made the stereo image very flat and forward, however it does sound smooth and pleasant in ways. It’s pretty crazy how different they are. ---

Mac OSX does not support native DSD on USB output-with a Mac connected directly you can only play DSD files via DoP, so this has nothing to do with Audirvana.
