# arm64-specific override for the shared spotify-connect.service (see # hosts/audio-endpoint/configs/). The HiFiBerry Amp2 is the only ALSA card once # onboard audio is disabled (config.txt.d/hifiberry-amp2.txt), so hw:0 is safe # and deterministic here. The amd64 image ships with no equivalent override — # a generic mini PC's USB DAC enumeration index isn't knowable in advance, see # hosts/audio-endpoint/README.md's amd64 section for that one-time manual step.
