Hi!

I am running HiFiBerry Digi+ on top of the Raspberry Pi 2 Model B, but I am not getting anything on optical (TOSLINK) output.

First I have installed Volumio 1.55. When using 'Hifiberry +' or 'Hifiberry Digi' I2S drivers (NOTE: I have tried both options as I was not sure which of the two is applicable to HiFiBerry Digi+), I get no sound on my old Yamaha RX-V 450 receiver. (reboot was each time after making changes in Volumio). I found some threads discussing compatibility with old DAC's used in Yamaha receivers, but I am not sure this is applicable at this moment, due to the reason that I don't see any signal on the optical cable. I don't have any electronic measuring equipment to confirm, but I see that the optics in the cable are not showing any red light. Would this be enough to confirm that no signal is sent via TOSLINK?

I have also used the Raspbian image with test tone generator with the same result. I hope I was doing it right. Image was applied to the SD card and device was started. That's it, right?

When I use Volumio with the standard Pi's 3.5mm audio jack, all is working correctly.

I haven't had the chance to test the coaxial output yet, but I plan to do it.

Do you have any advice on the next steps?

Thanks!

  HI,
  
  does the LED on the Digi light up? What sound card is being detected with the test tone generator (it is shown on the screen).

  Hi!
  
  yes, green LED on the Digi board is on. It is marked with 'D1'.
  
  Here is what I see when running the test tone generator:

  Ok, looks good so far. If the optical output does not light up, it seems to be damaged. We need to replace the baord. Please send an email with your order number to info@hifiberry.com
