Hello all. I got new RPi2 with Openelec 5.0.3 and DAC (RCA) module and I can't make it working ! I can't find etc/modules in Openelec to modify it, etc. Could you please give me instructions what to do step by step to have DAC working? I am completely new with RPi and Linux so please describe all steps as clearly as possible to the person not familiar with Linux. I turned on SSH in RPi and got PUTTY.

  OpenElec 5.0.3 is using a newer kernel. Check out our guide here:

  Thank you Daniel, now I can see the hifiberry card in Openelec system, but the problem is that if I select hifiberry output I still don't have signal on RCA outs and what is worse, the sound on HDMI now is missing. One thing is that I have connected quite weak power supply - 1A. Could it be the cause of problems ?

  No, the power supply shouldn't be the problem here. Did you configure the hifiberry-dacplus ? Note that the DAC and DAC+ use different drivers. Therefore you need to configure dacplus.

  No, I configured hifiberry-dac. As I have a device on PCM 5102A chip I supposed that I should configure DAC not DAC+. Am I right ? My Raspberry is Pi 2 model B.

  The old DAC won't work with the Raspberry Pi 2. You need the DAC+.

  That is a huge pity for me. But as Hifiberry on 5102A can be just standalone DAC for I2S, why I can't use it as standalone DAC connecting pins Vcc, Ground and 12,35 and 40 on my RPi2 ? Why RPi can send I2s signal and not RPi 2? Could we anyway have any solution to combine RPi 2 with HifiBerry DAC?
  Best regards,

  While you can try to connect pins, we can't support this. I'm sorry, but this kind of configuration often results in problems of all kinds that are hard to debug and we cannot give support for this. We have specifically developed the HiFiBerry DAC+ for the Raspberry Pi A+/B+ and 2B.

  Dear Daniel
  
  After your advice I'm going to buy Hifiberry DAC+ for my RPi 2B at your reseller in Czech Republic. Could you please confirm that it is checked that DAC+ works with RPi2 and the sound is both at RCA outputs of DAC+ and also remains at HDMI on TV set?
  
  Best regards

  No, with OpenElec and XBMC you can output to sound only to a single sound card. You can't output to the DAC and HDMI in parallel.

  It is a big inconvenience in my opinion. Is it caused by partucular hardware reason, or there isn't software solution yet, and hopefully will be solved one day ?
  Then could you tell me please if I will have a choice in audio output settings of Openelec after I plug in DAC+? I mean if there still will be choice between HDMI and DAC+. For me it is important to have a possibility to watch tv with sound from HDMI.
  
  I am asking so many times, because the total cost of DAC+ for me will be around 50 Euro together with shipping and taxes.
  
  Best regards

  Hi Artur,
  
  this is a software issue. I wouldn't expect this is on top of the list for the Kodi developers. Therefore I don't expect this to change soon. You might directly contact the Kodi developers here: http://forum.kodi.tv/
  
  You can change the output between an ALSA sound card and HDMI in the settings from HDMI to ALSA and back.
  
  Best regards

  Dear Daniel
  I ordered today DAC+ from your Czech reseller. To be 100% sure that it will go with my RPi2 B: are there any different versions of DAC+ (lets say newer and older) or there is only one, and works both with B+ and 2B ?
  Best regards,

  There is only one DAC+ version, just with different connectors (phone or RCA). It works on B+ and 2B.
