Andreas Baldamus Hi there,
is DIGI+ PRO a bit of new hardware or is it DIGI+ with the OS enhancements?
Thanks for answer in advace Andreas

HiFiBerry team Dear Andreas,
the Digi+ Pro is a new piece of hardware. Check out our news article here:

RBM Great way to introduce the product – just ordered one. :-)
I'll be using it primarily with Roon – I guess the HifiBerry RoonReady image is not up to snuff yet, so I'll be running Roon Bridge on Raspbian?
-
HiFiBerry team Hi,
we will work on a Roon update. If you are already using our Roon version 1.0.4, you will get the update automatically.Best regards,

Matt I'm interested in the possibility of adding a jack for external power. But I'm a soldering noob. Are there any guides available?
Thanks
-
HiFiBerry team Hi,
you mean a soldering guide? You will find a lot of videos about on YouTube.
Best regards,
Daniel -
Matt Sorry, to be more specific, I meant about selecting which parts to use and how/where to attach them to the board. I'm guessing this is something more experienced people might be able to work out for themselves.
-
HiFiBerry team We will provide documentation about this in the future, but not at the beta-test stage.
Best regards,

Scott Kramer Hi Daniel,
Awesome! Have one on order to test. Are there any onboard regulators? What does the 5V power... on the Digi+ it was just the optical.
Are you providing a part# for a BNC jack yet?
FYI, I let the piCorePlayer guys know about the driver, 4.4.19 will be in it next release (3.0x)
Thanks!

Micke Ollars Well, hardware arrived and when i found the necessary instructions it worked just fine!
I was a bit confused as i expected Roon to display the correct name for the endpoint, but i now see that it will display the very same name as previously:
snd_rpi_hifiberry_digiThanks guys for the very fast delivery!
-
HiFiBerry team Hi Micke,
looks like you're the first person using it.
I guess, you've build you own Roon endpoint. You could also use our Roon client (however, it won't distinguish between Digi+ standard and Pro).

Daniel -
HiFiBerry team @Scott: There are no onboard regulators. 5V is only needed for the optical output, all other parts of the circuit are powered by 3.3V.
We don't have a part number for the BNC jack yet, but we will have these available in our shop in the future. They come from a small Czech company.Best regards,
Daniel -
Micke Ollars :) I might as well add my Digi+ Pro has landed on top of a Pi3 with a Jessie Lite distro along with the necessary software for acting as a Roon Bridge.
I have two questions:
1. What does the jumper do? J1
2. What is the pinout for I2S delivery?

pl_svn hi Daniel
seen my Digi+ Pro was shipped today :)
while waiting for delivery... I can prepare a microSD card using your Roon image, right?
then I will also need to perform the linux kernel update steps?
-
HiFiBerry team @Micke: J1 create a high-resistance electrical connection between the Digi+ ground and the DAC ground. This is needed for some DACs that aren't grounded.
We will have the documentation for the I2S header ready soon.
@pl_svn: Our Roon image updates itself automatically. You don't have to do anything. Just install it. It will reboot some times in the beginning until it has been updated to the latest version. -
pl_svn thanks Daniel
can't wait for my Pi and Digi+ Pro to be delivered :)

Peter Hi Daniel,
I have a linear power supply (SBooster) with 5V I want to use with my digi+ pro. The digi+ pro connects using Coax for audio.
Do I have to supply both 3.3v and 5v on the digi+ pro? What about the raspberry pi Micro USB power connection is it still necessary?
My goal is maximum audio performance!
Best regards
Peter
-
HiFiBerry team If you want to use a linear power supply, use a 3.3V linear power supply and feed only the Digi+ electronics. With a 5V linear power supply, the audio circuit will still be powered from the onboard regulator or the Raspberry Pi.
If you just want to use your power supply, you can feed the power to the P1 connector. It will power the Raspberry Pi and the Digi+
Best regards,
Daniel -
Peter Hi Daniel,
thanks for your fast answer.
So there are two options:
1. Feed the 5V Digi+ Pro connector: Powers Pi an Digi+ including TosLink Connector. No other power supply is needed.
2. Feed the 3.3V Digi+ Pro connector: Power supply for the pi is still needed (micro usb), 3.3V connector feeds only the Digi+ and only COAX-Connection is working.
I have a few more questions:
- What option among the two mentioned is the best for maximum audio performance?
- Can you recommend any 3.3V linear power supply?
- Are there any other tweaks/options to improve audio performance with digi+ pro?
- Is It a good idea to use my 5V SBooster for powering the pi (5V) and digi+ pro (3.3V Connector), with some sort of power regulator both at once?
Thank you and best regards
Peter

Olivier Vicent Hi, i have ordered the Digi + Pro ßeta board.
Is it working with Moode audio on Pi 3 ?
i hope someone will be able to get it working with Moode audio ...
;-)
-
ombjerkvik I think it will work out ok since the latest version is built on kernel 4.4.19
I have tried and it recognize it. However I have not yet tried if it plays. I want to tap i2s to my soekris dac and waiting for some "instructions" how to do that.
Moode is not my favourite distro either. Too "sluggish".

Micke Ollars @Daniel
"You could also use our Roon client"I tried the Roon Hifiberry image today, but no sound was available using your image 1.0.4 and the Digi+ Pro on a Pi2?
The endpoint Surely showed up in Roon as a certified endpoint, and playing was OK, but no sound on the coax output?Is there any way i would know that the image was finished updating itself etc?
-
Olivier Vicent Hi, Thanks for your reply.
what is your favorite distribution ?

tjw321 With the latest Moode (2.7) the digi+ pro works "out of the box", pretty much. There isn't an entry in the i2s config for the dig+ pro but selecting the digi/digi+ driver seems to work. The kernel is the correct version in 2.7 so you don't need to update the kernel. Make sure that you don't have any USB DACs etc plugged in because Moode assumes that the i2s device is the first one and the USB DACs get listed first - I lost some time figuring that out...
I am, however, having intermittent wifi issues with an RPi3. At first I thought it may be the card blocking the signal, but it's too intermittent for that. Is it possibly related to the known problem with the DAC+ Pro? It seems to happen most when playing hi-res files which will use the 48kHz clock rather than the 44.1kHz one. I'm currently working around it by re-sampling everything to 44.1kHz. (I've only had the card for a few hours so I don't have much more than this at the moment - and I'm away for a few days soon so it'll probably be a while before I can trouble-shoot much more).
Moode sounds amazing via the digi+ pro and my Chord Mojo, BTW :)
-
tjw321 Hmmmm. The resampling doesn't work as well as I'd thought. Even with the re-sampling, the bandwidth drops drastically as soon as I play something, and eventually the connection drops. It seems a little worse with hi-res files, but even 16/44.1 files will degrade the wifi to the point where it drops.
A bit more info. The ethernet connection ends up getting both ip addresses and so the wifi behaviour I was seeing is actually ethernet behaviour. Hi-res files are currently killing my ethernet connection, but 16/44.1 files don't. Resampling enables hi-res files to be played without loss of connection. These are intermittent behaviours so it's difficult to pin down, but right now, wifi doesn't work at all, and ethernet only works with resampling to 16/44.1. I'll keep testing later and see if I can pin this down better.
-
HiFiBerry team @Micke: Unfortunately there is no option in the Roon software to display the version of the client. We will work on a feature to display the detected sound card and client version on screen.
@tjw321: Thanks for the feedback on the WiFi. We will look into this.
Best regards,
Daniel -
tjw321 Thanks, Daniel.
I've done a little more testing and if I turn off the RPi3's wifi then the ethernet behaves itself. Playing hi-res music with the wifi turned on causes both connections to break.
@Olivier: If you plan on using an RPi3 on ethernet using Moode, turn off the wifi chip in config/system before playing any hi-res music and I think everything will work okay.

Gerard Koopman Anyone tested the Picoreplayer 3.0x already? I am not able to get it working correctly (no sound).
Hope somebody has a tip or trick for me. Maybe kernel is not ready, should be 4.4.19 and 3.00 is 4.4.15.
Anyone?
-
tjw321 I had a quick go at Picoreplayer and got stuck at the same point as you. We need to upgrade the kernel, but i haven't figured out how to do that with picoreplayer yet.
Looks like the kernel isn't built yet:

HiFiBerry team You can't simply upgrade the kernel on Picoreplayer. The developers have to create a new release.
