Luna (moonlight) can't change audio output to HiFiBerry Digi+ (S/PDIF output)

Help and Support Raspberry Pi

I have a HiFiBerry Digi+

This outputs sounds over S/PDIF to my amp.

When I stream games to the Pi via Luna there isn’t an option to choose audio device, so on the projector there is no sound (I assume the sound is going via HDMI the default ALSA device).

I how do I install aplay to check the audio devices as I’m getting on command not found on OSMC.

https://www.hifiberry.com/guides/configure-osmc-for-hifiberry/

Notes:
To get the HiFiBerry Digi+ working in OSMC you have to edit config.txt adding the following line:

dtoverlay=hifiberry-digi-overlay

Also an update in January/February required this to be adjusted too:
dtparam=audio=off

sudo apt-get update
sudo apt-get install alsa-utils

Thanks Sam. These are the audio devices:

osmc@Lounge:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sndrpihifiberry [snd_rpi_hifiberry_digi], device 0: HifiBerry Digi HiFi wm8804-spdif-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0

Within luna settings>select audio device
It only lists sysdefault

It seems to be loaded:

Looking under \luna-master\resources\lib\model\audiodevice.py

This is probably the file which needs adjusting to recognise the soundcard, currently it contains:

class AudioDevice: def __init__(self): self.name = None self.handler = ''

That’s fine.

You turned ALSA off for snd-bcm2835, so you will only have one device now. You may need to configure asound.conf manually.

I don’t have a HifiBerry for Pi2/3 so can’t test this for you. This is beyond the scope of the OSMC forum. Maybe you will have more joy on the HifiBerry forum as other distributions use ALSA in a more involved way than

Thanks Sam, it might be a luna issue - will report back with any solutions.
