franny73 · January 1, 2019 at 3:58 PM

Hi all,

I am currently trying to install snapcast. It just works during installation session. After reboot Hifiberry is not available as audiodevice ..

Does someuse the same combination ... any hints what I can try?

Thank's in advance,

Franny

====================================================================

Conclusion:

In the meanwhile it seems to work ....

Solution: I configured in SnapClient Add On settings that Soundcard to SYSDEFAULT and that Kodi stops SNAPCLIENT during playback

Do you have further hints for improvement or stabilization?

Thank's anyway!

Hi,

have to get back on this ...

Actually still have issues ..

SNAPCLIENT is stable working ... but I can't select HifiBerry ALSA Device in KODI System Audio settings .. there are only the RPi devices like analog and HDMI. When I deactivate SNAPCLIENT Add-On ... ALSA Device is immeidately available in KODI settings ...

Any hints what I can try ... ?

Thank's in advance, Franny

I will do some testing with a Hifiberry DAC+ tomorrow.

In the meantime you could ask Hifiberry how to share a Digi with several processes.

Hello franny73,

Sorry for the late reply, but I have been busy elsewhere.

Nevertheless, I have good news: I have managed to use a HiFiBerry DAC+ with both Kodi and Snapclient.

Here is how I have done:

1. I used the command mount -o remount,rw /flash; nano /flash/config.txt) to add the following line to /flash/config.txt:

Code

dtoverlay=hifiberry-dacplus

2. I rebooted for the changes to take effect

3. I used the command nano /storage/.config/asound.conf to create the following asound.conf:

Code

pcm.hifiberry { 
  type hw
  card 0 
}

pcm.shared_hifiberry { 
  type plug 
  slave.pcm "dmixer"
    hint {
        show on
        description "Shared HiFiBerry"
    }
}

pcm.dmixer { 
  type dmix 
  ipc_key 1024 
  slave { 
    pcm "hifiberry" 
    channels 2 
  } 
}

ctl.dmixer { 
  type hw 
  card 0
}

Display More

4. I configured Kodi (Settings/Audio/Audio output device) to use ALSA:snd_rpi_hifiberry_dacplus, Analog

5. I configured Snapclient to use shared_hifiberry

6. For good measure I rebooted again

You want to adapt step 1 to your card.

Let me know if the above works for you.
