searching the forum I found the information below
a) enable it in: My OSMC, Pi Settings b) reboot, c) Select it in Settings, System Audio Output.
Works great to a point. When I go to settings > audio output and change the “audio output device” to ALSA:default(snd_rpi_hifiberry_dacplusAnalog) it just freezes.
Clean install on OSMC stable version. No changes to anything other than installing via App Store Transmission.
Rebooted and tried again, same thing happening. There is a green light on HiFiBerry and both red and green constant on on the RaspberryPi
Will try to troubleshoot but ideas are welcome.
