[SOLVED] No audio for Spotify with USB DAC

[thexperiments]

I just saw the command moOde uses to start librespot in the logs and launched it manually via ssh.
Result seems to be a crash as soon as playback starts

Code:

sudo librespot --name "Kopfhörer Wohnzimmer" --bitrate 320 --initial-volume 100 --volume-ctrl fixed --cache /var/local/www/spotify_cache --disable-audio-cache --backend alsa --device "_audioout" --onevent /var/local/www/commandw/spotevent.sh -v

Code:
