thanks, that’s way above my pay grade, at least happy to see someone looks at this!
In other words it’s no use trying on the Odroid?
I hope one day it will work ;o)

I’m thinking to try myself this custom kernel, but it seems Moode and maybe PicorePlayer guys will apply this kernel , let’s see.
and IT WORKS!
DSD128 now works with picoreplayer since version 3.02
so happy!
new listening sessions to come ;o)
weird thing though is that although DSD64 is reported as DOP DSD64 1Bit on the display,
the DSD128 is reported as PCM 176.4k 24Bits which is the bitrate for DSD64 and not reported as dsd…
It does this with all my files, will try fresh test downloads on official sites see if my files are fakes…
YAY!!! That brings back the whole option for me to consider this. Without DSD128 I was holding off.
Linvincible said and IT WORKS!Just FYI: I don't know if I followed this conversation correctly, but if the DS's screen says PCM 176.4 24bit that's what the DS is receiving...DSD128 now works with picoreplayer since version 3.02

Thanks Ted, by listenig closely to the sound I am also convinced there is a pour downsampling done by the picoreplayer. So at least the files play, but still no dsd128 yet. This is fairly new though, let’s see if the guys at picoreplayer can fix it!

Linvncible,
Yes, Ted is right, it will behave diferently in Picoreplayer if you use some upsampling in ALSA paramters.
anyway
I did a comparative test between dsd64 and dsd128 tracks (same tracks distributed in both formats by nativedsd.com) using usb output of the Pi
I couldn’t sense any difference
Guess I reach the resolution limit for my system or my ears…
I can’t upgrade my ears, so I’ll have to verify this on another system!
Hi Linvincible,
I’m using I2S connection between PI3 and Directstream and for me is there some differences when PI3 downsampling to PCM format, I’m using some 2L music data that contains in both formats, I believe you should try I2s, it’s worth.
Hi Charles,
I didn’t like the sound via USB from the Pi to my former DAC (Oppo HA-1) The UpTone Regen helped in this case very much. I don’t remember if I have tested the Pi with the DS DAC via USB at all. The Regen is sold, I2S rules!
Did you hear about the Singxer SU-1? Though I was not impressed with a similar device (Gustard U12), I would like to give the Singxer a try.
or:
I have a SOtM sMS-200 now for Roon/HQPlayer, very happy with the sound but I need a more powerful (and fanless) mini-pc for running HQPlayer. So, the Singxer still must wait. Not sure if I need it at all between the sMS-200 and DS DAC. I will be waiting for ted_b’s report about feeding the Singxer from the µRendu:
Holo Audio Spring Level 3 Kitsune Tuned Edition R2R DAC Review
PART TWOFirst off, I decided to buy the Singxer SU-1. It is high value at $399 and offers a great I2S signal path. I will write more about I2S sound vs USB sound soon.
, … but I will try and feed the Singxer from the microRendu just to hear what it does. I will report back.

Hi Mario,
No I haven’t seen this but I don’t see the point of using the USB interface to put it anywhere else than in the USB input of the DS ;o)
For the moment I’m testing an Odroid C2 board with Volumio, I already have the I2S working on PCM and DSD64 but it fails on DSD128. But not like with picoreplayer on the Pi: no downsampling here, just that the signal is recognized by the DS as PCM 16*352.8 instead of DSD128, silence ensues.
Volumio guys tell me I need the DAC supplier to deliver a driver, although I don’t understand what a driver for I2S would be if not generic…
I’ll ask Ted in another thread!
Linvincible saidThe USB connection is not always the best (sounding) solution especially when a Pi is the source. The USB input of the DS DAC... as I have read somewhere the DS DAC takes benefit of an USB Regen. Not to forget about the LANRover. So in this case a Singxer with the newest XMOS USB interface and offering I2S output might help as long as DSD128 is still not possible via I2S from the Pi or the Odroid.Hi Mario,

About the I2S drivers… hmm. In the Pi settings you can choose between the generic and several other ones. I have chosen the HifiBerry DAC+ (and Pro) but the generic driver works in my setup, too. All the other ones don’t work here, neither the other HifiBerry drivers.
I just switched from my streamer based on RPi3 to an Engineered Network Media Renderer board, connected via AudioGd output module.
This is a great, great I2s source for our DS.

Great to know, how did you set this up?
What OS is it using?
what is the max DSD rate supported by I2S output?
My current system is minimal now.
Minimserver on my Qnap Nas -> ethernet connection -> NMR board (with linear psu) -> I2s output to AudioGd module -> hdmi cable -> DS.
No OS… the board is a media render, it doesn’t need it.
I’m testing some control point apps (Linn Kinsky, Audionet, Plugplayer, Myaudiostream, ArkMC… and more).
I have no issues up to 24/192 and DSD64 (DoP) and, as I wrote, it sounds superb.
Playing 24/352 and DSD128 files (both supported by NMR), the DS screen displays half resolution (24/176 and DSD64) and sounds half speed.
according to their webpage their board is capable of only 128 fs
“support for DSD audio at 64xFS (2.8224MHz) and 128xFS (5.6448MHz)”
DSD128 needs 384 fs according to Ted
That’s why…
Thanks Linvincible
Hi, I’m using a RPi3 with Moode connected in USB to the DS and I’d like to implement an I2S solution. From your experiences, DSD128 will not work but it is mandatory for me.
Has any one tested the new Kali Reclocker boards for the PI with an Audio GD I2S to HDMI ?
https://volumio.org/product/allo-kali-i2s-reclocker/
Looks promising as this version of the board has quality 44/48MHz Clocks that supports 384KHz playback, however the technical spec seems to be for the one which supports only 192Khz playback. Confusing…
Hi Patrick,
I’m pretty sure it won’t work, I’ m even ready to bet a kali reclocker ;0)

You like play 
What makes you think that ? Is it related to the Linux kernel issue ?
I’m using moode but I’d be ok to change for something else based on a fixed kernel eventually.
