But I am able to play 384kHz PCM now in true sync via Roon. Problem is with DoP limitaion in Roon.
RPi supports native DSD only through USB streamer. If you want to eliminate the DSD128 limitation, you have to use a USB. Both Roon and Volumio are.
If you prefer GPIO of RPi, only DSD through DoP will be available.

No Ian, I am absolutely happy with DSD64/128. I have no DSD256 files at all in my music collection.
Hi Ian,
What DSD data rate were you using with your FiFoPi and DAC for you comparison tests? Which USB to i2s were you using? Full DSD conversion by Roon software or some other hardware that does PCM2DSD?
Thanks

BTW. Did anybody actually try OSF Bypass???
I mean. Usually the on-dac filters are known for not being highest end.
Perhaps the OSF-B feature is rather low hanging fruit.

I am still on true sync mode.
Just tried the OSF bypass. OLED indicates correctly both PCM and DSD stream.
There is no sound from PCM (silence at any volume including 0). DSD plays but with big amount of "white-like" noise at DSD64 and much less at DSD128. But both can be good enough sonically if to reduce the volume to ~-6dB at DSD64 and ~-2dB at DSD128 (volume regulation works).
In OSF-B you'd need to feed 8xFS according to DS. 44k1->352k8
Volume control and Mute wouldn't work anymore.

And what is the better way to do it within Roon? There is no resampling pluging in DSP section of Roon. HQPlayer?..
Hmmh. I don't use Roon. HQplayer has a good rep.
However.
I'd say the vast majority is using sox/libsoxr on piCorePlayer, Moode, Volumio
- the stuff that most people areound here use. sox/libsoxr delivers absolute
top notch results.
BUT.
Highest quality resampling on the PI is not what I'd recommmend. I've done and shown the benchmarks.
The PI is simply to slow. (I havn't tried it and didn't run the benchmarking on PI4 and aarch64 (yet) )
As a test you could simply try offline resampling a test-file first. And that one you can play back.
This way you'd avoid any huge investments or configuration changes.

Yes, there is an option in Ian's controller.
But. RoonCore is not on the RPI. In my case it runs on IntelUp board (ubuntu 19.04). Rpi - is just a bridged output device for Roon (Roon Bridge).
I have tried many different players like: Volumio\Moode\RuneAudio\Max2Play(with LMS), but Roon is my favourite - it has much friendly interface with much more interactive searching engine.
I will try to convert upsampled by x8 files in foobar2000+sox and then will play it in Roon.
But I am not sure about (Roon+HQPlayer on IntelUp) capable to send the stream to rpi (briefly noted that Roon and HQP uses different protocols for sending audio futher to network). Seems it has many other gaps in return of upsampling features...

There is, it's called Sample Rate Conversion
Next report:
After switching S2 pin 1 of ESSController to "Auto mute disabled" (On-position of switch) any PCM streams works OK (without any up-sampling). Volume not works on PCM - always at maximum (no matter what indicated on OLED).
DSD64\128 works as described earlier (with some noise at max volume and volume is adjustable).

Some one try feed rpi with batteries? Feed with lifepo4 is not the best for me. I try with 2 batteries of j3 and ldo lt1963. For me the best result.
Great.
It seems that they (ESS) just recommend to run 8*FS because of the lack of filters then. There's still an IIR in the path btw. You can't get rid of that one.
You need to use SW volume control of Roon now. You had it configured for HW control I guess. And Sabre VC won't work anymore.

It won't work! SW VC on DSD simply doesn't work.
From what I read somewhere the Sabre DACs are not really native DSD DACs.
By applying a special trick they are able to offer that SW VC also on DSD.
The question is if PCM will sound better without the filters. Perhaps even better then DSD. 😀

🙂 The better music in my collection still in pcm, so I have not facing with DSD outperform over pcm even with OSF enabled. But I will try to compare OSFed PCM with non-OSFed PCM. One another funny thing - volume adjustment works for PCM in "offline" mode - I can set the volume level before playing PCM files 🙂
