It's almost the same asound.conf. For me it looked like the asound.conf / sound.conf file was just completely ignored by Libreelec.
I will continue to use libreelec on my "standards" Pis, but will keep raspbian on that precise one.

Well, I didn't manage to do it with libreelec so I installed a raspbian and made it work right away...

I bump this message in case somebody has another tip. So far I did not find a solution...

I tried to add bindings like this but with no success:

pcm.hifiberry { 
  type hw card 0 
}

pcm.!default { 
  type plug 
  slave.pcm "dmixer" 
}

pcm.dmixer { 
  type dmix 
  ipc_key 1024 
  slave { 
    pcm "hifiberry" 
    channels 2 
  } 
  bindings {
    0 0
    1 1
  }
}

ctl.dmixer { 
  type hw 
  card 0 
}

I do not really know what bindings are used for but I took example in alsa documentation

I have that in the config.txt:

# Hifiberry
dtoverlay=hifiberry-dacplus
dtoverlay=i2s-mmap
dtdebug=1

Hello,

I want to use in parallel Kodi and Squeezelite on the same libreelec RPI3 with an Hifiberry DAC Plus soundcard. I used to do that in the past but my SD card died and now I cannot set it up again.

The problem is that the hifiberry card cannot mux multiple streams. Kodi or Squeezelite takes the card - whichever starts first - and the other cannot play.

It should be possible to configure alsa with dmix plugin. I tried the following in /storage/.config/sound.conf and /storage/.config/asound.conf

:

pcm.hifiberry { 
  type hw card 0 
}

pcm.!default { 
  type plug 
  slave.pcm "dmixer" 
}

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

ctl.dmixer { 
  type hw 
  card 0 
}

But this does not seem to have any effect.

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dacplus], device 0: HiFiBerry DAC+ HiFi pcm512x-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

It looks like the config file is completely ignored. I did not find anything useful in the logs, but I am not sure of what to look for.
