Digi+ not working?

Hello Forum members,
I own a HifiBerry Digi+ which I intended to use on my RasPi B+. I tried some time, but without getting any tone out of it. I'm using the preconfigured image (OpenElec 4.1.6) I found here. The green LED on the Digi+ is on, but nothing else (Must there any light out of the optical socket?). I also checked the Toslink cable - this is OK.

Output in my dmesg:

The drivers are loaded and I did not saw any error message so far.
Can somebody help me out here? Any help is highly appreciated.

Man thanks in advance.

  Hi,
  
  you might need to enable the output in the settings. However I would recommend to use the new OpenElec 5. You can download it directly from OpenElec and configure it as described here:

  As mentioned I'm still on the preconfigured OpenElec image. I hoped it would work out of the box.
  Is this change also valid for 4.1.6?

  No, for the preconfigured image, just enable the output in the settings.

  Ok. Thank you. But - as expected - no change. As soon as I re-enable the output using the Digi+ there is no sound anymore. There is no usable signal on the optical output available my receiver can use. Of course I used this setting before writing here, but for now it is set back to HDMI. Otherwise the RasPi-STB is completely useless.
  I will try OpenElec 5 soon and report about the results.

  What is the output of aplay -l. I think there was a bug in our OpenElec version.

  I found the time to prepare a card with OpenElec 5.0, configure the Digi and do a quick test.
  Unfortunately same result - silence.
  
  Here the output of aplay -l:

  Does the optical output light red? Do you use the optical or the Cinch output?
  What device do you connect the Digi to?
  
  Best regards

  Yes, the red light is on (OpenElec 5). I seem to recall, that it was not on with the preconfigured image. But I'm not sure.
  I use the optical output. Additional to this I also connected the chinch output to a different input of my receiver. I cannot hear any sound on both. The only difference is that on the optical line there is some white noise, but only perceivable on high volume.
  I use a JVC RX-ES1.
  
  What wavelength does the optical output of the Digi+ use?

  Toslink uses about 650nm. Please test the board with our test image from here:
  https://www.hifiberry.com/guides/sd-card-images/
  
  It could be an incompatibility of the Digi and your receiver. We have seen rare cases like this, but mostly with old receivers and DACs from the 1990s.

  Here the technical data of the receiver. It is now around 10 years old.
  Audioeingang (DIGITAL IN)* :
  - Koaxialanschluß = DIGITAL 1 (DVD): 0,5 V(p-p)/75 Ω
  - Lichtwellenleiter = DIGITAL 2/3 (STB/TV): –21 dBm bis–15 dBm (660 nm ±30 nm)
  
  The TV and the AppleTV are able to send a usable signal over the TOSLINK to the receiver. Both tested with the same cable and same input (DIGITAL 3).
  
  Does the possibly incompatibility make the whole Gigi unusable for me or only the optical output?
  
  I started with the preconfigured image (see my first post). As far as I can see it is the same base version. Did you rebuild the image recently?

  Hi Ronny,
  
  I do not mean the OpenElec image, but the test tone for DAC and Digi. This helps to find out if this is a configuration issue or a hardware incompatibility.

  I made the test with the suggested image: still no sound using the optical connection the my receiver. Which information do you need to further investigation?
  
  Thank you!

  Hi,
  
  the electrical output is working, but not the optical - correct? Does the optical output light red?

  I have the same issues with my RP2B running openelec 5.04 in combination with a JVC receiver.

  Hi,
  
  what exactly is "the same issue"? What is working, what isn't? Did you test the hardware with our test image?
  
  Best regards

  here is an overview of what I tested with my RB2B + Digi+ + openelec 5.04 + JVC RX-8012R
  
  0. verified red light from optical interface on Digi+ bioard --> yes there is red light coming from the interface
  1. green led is active on Digi+ board
  2. hifiberry sd card test image --> did not test because it did not boot
  3. hifiberry raspian test tone generator --> test tone played as seen on the TV but no sound heard from receiver
  4. tested with optical cable --> receiver detected DTS stream but no sound
  5. replaced optical cable between Digi+ and JVC receiver --> still no sound
  6. tested with technical (coax) cable --> receiver detected DTS stream but no sound
  7. replaced technical (coax) cable between Digi+ and JVC receiver --> still no sound
  8. rebooted RP2B several times, verified settings --> still no sound
  9. when switching to analog outpot within kodi sound is heard via the receiver, via a separate analog audio input
  
  aplay -l command show this

  Hi,
  
  if the red LED turns on, the output is transmitting a signal. What is the "hifiberry raspian test tone generator"? Is it our test image? Because you said, the test image is does not boot.
  
  As the card is recognised and the output is turned on, thre is only a slight chance, that the board itself is defective. However, it could be an incompatibility of the board and your receiver. We can replace the board, but there is a good chance that the same problem will occur with another board. Alternatively we can take it back and give you a refund (if you bought it directly from us).
  
  Best regards

  Hey there,
  
  I am following this discussion and as I have been testing quite for a longer time now my rpiB+ and digi+ with different images and the newest OpenElec release (5.05), as well as the test-tone image downloadable from this site I unfortunately have to add my connected receiver (marantz sr4400) to the "not working receivers list" I guess. I tried the optical as the electrical output and although the green led of the digi+ and the optical outputs red light is working still no data is send to the receiver ... any ideas? (by the way, music is easily played through hdmi and analogue output)

  Nizolai

  Dear Nicolai,
  
  if it is not working with the test image and the optical transmitter seems to work, there is nothing else you can check.
  I start thinking that older receivers might have a problem with the 24bit data stream, but as long as I don't have one of these here, there is nothing I can do about it. You can return the board to us, we will refund it.
  
  Bets regards

  Dear n0m0r3,
  
  this might be an incompatibility. I don't think we can do something here. Please return the board to us, we will refund it.

  Hello Daniel,
  it is really pity to hear that the both components are not compatible. Unfortunately I didn't by directly from your shop.
  Is there any chance we can solve the compatibility issue together? I cannot send you my receiver, but I could test some libs for you and send you any output you need. As mentioned in a post before the AppleTV and pretty new LG TV are compatible.

  No, we can't do any remote tests here. There is no easy way to change the driver and test things. I^m sorry. If you bought the board in the EU you should still be able to return it to your dealer.

  Just an update. We found out why the Digi was not working with the DSP-A2. Maybe your receiver has a similar problem.
  We will create a patch soon. Check out this topic:

  I have a PiFi Digi+ in a Rasberry Pi a friend lent me. It worked perfectly for 24 hours but now there is no red laser shining from the outlet on the board and no signal on the co-ax output. Any suggestions? The green LED on the board is lit.

  Are you talking about a genuine HiFiBerry Digi+?

  Daniel.

  I don't think it is genuine. On the HAT it says "DigiPi, PiFi Digi+ V1.0". I looked on the internet and saw a comment that it was a "Chinese copy of HiFiBerry Digi+". As far as I can see the Rasberry Pi board is genuine.

  I looked up the internet again and identified the HAT as: https://www.nielsmayer.com/xwiki/bin/view/Raspberry+Pi/Kodi+Audio+Heaven+With+PiFi+Digi+SPDIF+HAT+and+External+DAC#Information

  I guess if it's not genuine I can hardly expect you to help.

  Exactly ;-) But you can buy a genuine HiFiBerry Digi+ in our shop...
