Roon converts my DSD to PCM without any reason

Description Of Issue
My configuration was running with no issue until today.
DSD files are now converted to PCM 352 instead of being played natively by the DAC.

The DAC is set as NATIVE

Thanks for your help

Turn off Volume Leveling and Parametric EQ.

[Judelow]

It worked thanks but I am almost sure it was working with these setting on previously. Am I wrong?

[Steven_Goff]

Volume leveling and parametric EQ can only be done in PCM.

EDIT: it appears that Roon can perform parametric EQ on a DSD signal converted to an “intermediate state.” The sigma-delta modulator then converts the signal back to the one-bit stream. This reportedly maintains the attributes some favor in DSD.

OK thank you very much

Then what does this mean?

Parametric EQ and DSD playback

We do indeed process DSD without performing a DSD->PCM conversion first. The signal path is reflecting that accurately. I’m going to explain how it works–keep in mind that there are some subtle technical details here, and some background knowledge is required to understand them fully. Processing DSD isn’t nearly as straightforward as processing PCM. With the exception of a few simple operations, you can’t process it directly in the 1-bit representation. There are more steps involved, but it’s p…

Thanks
That is very technical. I am not sure to get it full.
I think I was in the case of BrianW before.

[Judelow]

I think I found the solution
This need to be enable

To do that

Glad you got it sorted. Do you hear any difference?

[Judelow]

Hi Daniel
Parametric EQ and auto leveling, yes
But dsd or pcm, I could not tell the difference doing an A/B blind test. But I am just happy to use all capabilities of my Dac and be the one to decide which format I want to listen.
