Purchased a Justboom DAC Hat a while back, along with a PI 3B+. Was going to install OpenElec, but found out the latest distro isn’t compatible with the Pi. I ended up going with LibreElec, which has been working great with it.
I did solder the IR receiver onto the Justboom DAC but found it wasn’t responding to a couple remotes – I have a Flirc dongle that worked fine though, so I have Lirc disabled for now. I might spend more time trying to get it working later, so I can use the Flirc dongle elsewhere.
