colorado.native Posted February 6, 2019 Share Posted February 6, 2019 Just starting my build and I have three questions: 1) Is the DigiOne compatible with the new Raspberry PI 3 Model A+?; 2) Will both items fit inside the Allo Aluminum Case for the DigiOne Player? and finally, 3) Any issues I may expect from this new build? I'm planning to use RoPieee and set up a Roon endpoint. Thanks. Link to comment
Popular Post TomWoB Posted February 10, 2019 Popular Post Share Posted February 10, 2019 Hi all, this weekend I built my own "DigiOne Signature" with a "DigiOne Standard" 😀: Why: just-for-fun I don't like to power the Pi "via 2 boards" with tiny connectors I want to reduce the usage of such tiny connectors as less as possible (not for data too) I like the PCB of the standard DigiOne much more than the two Signature PCBs (especially the "empty dirt board" 😒) I like LT3042 power more than Supercap power ... and DigiOne Signature vs DigiOne Standard is toooooooooo expensive Regards Tom nbpf, richard_crl032 and Molins 1 2 Link to comment
Dr.J Posted February 11, 2019 Share Posted February 11, 2019 Very clever, Tom and nicely implemented .... Link to comment
TomWoB Posted February 11, 2019 Share Posted February 11, 2019 Yes ... and absolute no problem regarding "not enough power" (no flashing power light on Raspberry Pi anymore) ! When I have a look at the power discussion on "DigiOne Signature" thread (Page 32f) I lean back and relax 😁. How to solder power direct on Pi I already described here: Where to solder on Pi User guide The soldering points doesn't look perfect, but they work very well (large area has to be heated). Btw: I'm new in this forum, is there a way to edit posts again (e.g. for fixing typing errors)? I can't find an "edit" button(?) Link to comment
TomWoB Posted February 19, 2019 Share Posted February 19, 2019 Hi all, with my "power split" (see post #379 above) I did some measurements (current in ampere) to see how much power is really taken by a Pi/DigiOne. My setup: Pi-2B 1GB v1.2 (yes, an old one, I don't want any WiFi on a Pi for audio) moOde 4.4 http://moodeaudio.org/ DigiOne 1.2 CPU GOV = performance (always runs at 900 MHz = max speed) all additional services switched off (Airplay, Spotify, Squeezelite, UPnP client, DLNA server) 1) Pi only (SD card only, no USB-device attached) booting: 0.400 A (max) idle: 0250 A (stopped) playing 192 kHz track from SD card - 0.260 A (min) - 0.265 A (average) - 0.500 A (max = file access) 2) Pi with 1 TB SSD (Samsung 840 Evo, attached on USB with ICY BOX IB-233U3-B) idle: 0.370 A (stopped) playing 192 kHz track from SSD (USB) - 0.380 A (min) - 0.450 A (average) - 0.900 A (max = file access) 3) DigiOne only (clean side, DC-DC converter removed, external power) idle: 0.018 A playing tracks: - 0.036 A (44.1 kHz) - 0.038 A (88.2, 96, 176.4, 192 kHz) Conclusion I never saw current > 1 ampere, which shows that there are not so high requirements for a linear power supply (LPS) ! ... and how much takes a "complete normal DigiOne"? The DC-DC converter datasheet shows an efficiency of 70%, so we have to add approx. 0.060 A for the DigiOne to the values of 1) and 2) above. kotlarix 1 Link to comment
Molins Posted February 20, 2019 Share Posted February 20, 2019 I'm having severe problems when playing DXD and even DSD64 on my Digione/VolumIO combo. Songs which do not make any probs on my iDSD make hell of (white) noise under Digione ....... Do you all play highres DXD and DSD without problems on your Digione? Actually it does not matter which DAC after the Digione I use, the noise appears allways on identically the same positions and duration, some only seconds, some during 20-30 seconds, allways the same position, only on those DXD and DSD so far ..... strange....!!!!!

RX8R3ROD Posted February 20, 2019 Share Posted February 20, 2019 Sorry to hear you’re struggling with the Signature. Unfortunately, I’m pcm only, but someone should be along soon who can help. Link to comment

Try with DoP. DSD64 will will work properly. Make Audio Resampling off. Higher DSD rate files Mpd uses above 100% cpu core, noise may be related to that. Allo.com Tech. Support Link to comment
Molins Posted February 21, 2019 Share Posted February 21, 2019 Yes, resampling was always off and think I tried both ways DSD and DoP but will give it again a try tonight. Thanks. Link to comment
Molins Posted February 22, 2019 Share Posted February 22, 2019 I played an album which consists of 12 DSD64 and same 12 DXD songs (once you purchase the higher res the vendor delivers also the lower res for free). 4 DSD and 8 DXD make problems under mode DSD Native and only DXD files (which VolumIO shows as WAV/352) played with exactly the same errors under DoP, mode DoP didn't play the DSD64 files (this is not normal, isn't it?). No matter which DAC after DigiOne I use, the errors are allways the same. Resampling is allways off. I then played some FLAC192 and again, errors audible in certain songs. No songs do problems with the other DAC I own like iDSD or a DAP. So all in all I think for High-Res lovers this combo DigiOne+VolumIO is quite useless. Link to comment
sihctr Posted February 22, 2019 Share Posted February 22, 2019 I don't do DSD, but I tried out several FLAC 24/192 from 2L just now via my DigiOneSig+Volumio and they play just fine. So there might be an issue in your chain (coaxial cable? faulty digione?). Please note that ~24/192 is the rated limit for SPDIF IIRC. So that creates limitations for DSD/DXD files. I think DSD64 should work, not so sure for DXD. Others, feel free to chip in if I am mistaken! Link to comment
nbpf Posted February 22, 2019 Share Posted February 22, 2019 I never had any problems with the DigiOne or with the DigiOne Signature with 24/192 .flac files, either sent directly to the DAC or first transcoded by MinimServer to .wav. I am running both MinimServer and upmpdcli (and thus MPD) on the same RPi 3 B+ that hosts the Digione / DigiOne Signature. Link to comment
Molins Posted February 23, 2019 Share Posted February 23, 2019 Well, will try with different cables and different brands. Is it correct that DSD64 files do not play under mode DoP ? Link to comment
TomWoB Posted February 23, 2019 Share Posted February 23, 2019 Hi all, let's have a look at the hardware specification of the DigiOne. The S/PDIF transceiver chip is a WM8805, the audio data interface supports I²S, left justified, right justified and DSP audio formats of 16-24 bit word length, with sample rates from 32 to 192 ks/s. Now let's have a look at the audio formats: DXD is a PCM format with a sample rate of 352.8 kHz -> this can't run native on the DigiOne (without downsampling) ! Now let's check DoP (DSD over PCM): The original idea for DoP was to take groups of 16 adjacent 1-bit samples from a DSD stream and packing them into the lower 16 bits of a 24/176.4 PCM stream (see detailed explanation here). So we have the next limitation: DSD64 requires a 176.4 kHz PCM stream -> OK for DigiOne DSD128 requires a 352.8 kHz PCM stream -> NOK for DigiOne Conclusion: Only DSD64 can run native on a DigiOne (without downsampling) ... and the connected DAC must be DoP compatible too !

Nay Posted March 1, 2019 Share Posted March 1, 2019 Hi, Not sure how to view my usb hdd that is connected to my digione using android app? When i open my android app bubbleupnp i see the digione as Volumio renderer but when i select the library option i do not see the attached USB HDD ? Any help appreciated. Thank you. Link to comment
TomWoB Posted March 2, 2019 Share Posted March 2, 2019 Hi @Nay, I don't know the "bubbleupnp" app, but typically plugging-in an USB-HDD is not enough. You should also do something like (moOde): -> Configuration -> Sources -> MPD Database -> Update If you have "SSH Skills", the best will be to check if your USB-HDD is already successful "mounted" (otherwise bubbleup can't use it). After SSH login, call the command "df", it should show something like this: pi@moode128:~ $ df Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 122895396 44799216 73075024 39% / devtmpfs 470116 0 470116 0% /dev tmpfs 474724 0 474724 0% /dev/shm tmpfs 474724 8136 466588 2% /run tmpfs 5120 4 5116 1% /run/lock tmpfs 474724 0 474724 0% /sys/fs/cgroup /dev/mmcblk0p1 43539 22557 20982 52% /boot /dev/sda1 960380648 446965552 464560636 50% /media/USB-SSD tmpfs 94944 0 94944 0% /run/user/1000 Relevant is the line: /dev/sda1 960380648 446965552 464560636 50% /media/USB-SSD It shows that my USB-SSD is successful mounted. If you don't see such a line on your Pi, you have to mount the USB-HDD first! You can crosscheck with another command, if USB-HDD is "at least electrical successful conntected" to your Pi, call this command: sudo blkid -o list -w /dev/null pi@moode128:~ $ sudo blkid -o list -w /dev/null device fs_type label mount point UUID ----------------------------------------------------------------------------------------------------- /dev/mmcblk0 (in use) /dev/mmcblk0p1 vfat boot /boot 70F7-FA1D /dev/mmcblk0p2 ext4 / 3598ef8e-09be-47ef-9d01-f24cf61dff1d /dev/sda1 vfat USB-1 (not mounted) 982D-0FC0 Now you see that my USB-SSD is "connected to the Pi, but not mounted": /dev/sda1 vfat USB-1 (not mounted) 982D-0FC0 Link to comment

I just bought another download in DSD64 quality and again, 3 times white moise for a couple of seconds always the same positions, with no such errors when using a different source or a DAP. So it seems to me either Digione or VolumIO or both are not 100% capable of DSD64. Link to comment
Molins Posted March 4, 2019 Share Posted March 4, 2019 Ok, I tried now with moode instead of VolumIO and have the same errors like before, so it seems to me the issue is with my Digione, sadly...... Link to comment
Amgclk65 Posted March 10, 2019 Share Posted March 10, 2019 Hello. I want to purchase a Digione to use AirPlay to feed my LS50 wireless. My inputs don’t exactly match up with the outputs of the Digione. So I figured I could use a digital coaxial to optical converter. Now my question with that is. Will that affect the audio quality ? Also not to sure about using the bnc output of the Digione. Inputs for the LS50 are rca-toslink-usb. Anyhelp would be nice. Link to comment
