Current state of CAVA (visualizer) support (especially for streaming sources)?

  1. If you have sync issues, try reducing the number of bars and the frame rate, if the synchronisation improves it might be that the processor is struggling to keep up.

  2. I don’t know anything about shairpoint_sync, but maybe it is currently configured to use your soundcard directly and needs to be configured to use the softvolume output instead. See
    Airplay hardware volume control
