Hello!

...

However, a last problem persist. My dac is the W4S Anniversary Edition. When I use dsd (dsf) files, in plain moode player mode (without foobar) they are transformed on the fly in flac 192. Neither Dop or DSD native is  working at all. Moreover, it is rather unstable. In particular, when moving from a flac track to dsd sometimes there is just silence while  there is indication that the track is playing... Even worse, when I play music though the foobar setting the dsd does not work at all. The issue is present even in the 6.7 update.

So we're being presented a problem in two parts.

1) "in plain moode player mode (without foobar) they [meaning dsf files] are transformed on the fly in flac 192"

Question- does your DAC declare to moOde that it is capable of playing DSD material? If it doesn't, then DSD material automatically gets converted to PCM. When you play .dsf files "in plain moode mode" what does the Audio information screen (m>Audio info) say about it?

Here, for example, is what it says about my Khadas Tone Board which is also a DSD-capable USB DAC. Note the list of formats.

Code:

AUDIO DEVICE
Device:     USB audio device (Control)
Mixer name:     Khadas Tone Control
Chip:     
Interface:     USB
Formats:     S16_LE, S32_LE, SPECIAL, DSD_U32_BE
Platform:     Pi-4B 2GB v1.1

2) "play[ing] music though the foobar setting the dsd does not work at all"

DSD is not a base component of FooBar2000. You didn't tell us anything about the DSD component(s) you used or about the Playback settings you chose. I have no idea how FooBar2000 can be coerced into streaming DSD material via UPnP protocol to a UPnP Media Renderer. How do you know it isn't converting it to PCM before streaming to the renderer? (Debugging this part of the issue would seem to be a subject more appropriate for a FooBar2000 forum. I'm no expert on FooBar2000 or on serving DSD material via the UPnP protocol so I have nothing more to contribute.)

As an aside, I am concerned about your expectations after reading your final statement that "DSD works fine natively but the overall SQ is not as good." "Natively" means DSD material is sent directly to the DAC without any pre-processing. I don't see how changing from one player to another is supposed to affect the sound quality.
