Google Cast Preview image

Music Assistant has full support for Google Cast based devices. This includes Google's own hardware like the Google Nest speakers but also a wide range of other brands have "Chromecast builtin" support, like Harman Kardon, JBL, Canton and many others.

Features

  • Cast speakers are auto detected by Music Assistant
  • Music Assistant supports playing to cast groups which are created in the Google Home app
  • When using Google cast groups then perfect sync across players in that group is possible
  • Any physical control buttons on the device should be supported as well as voice control

Known Issues / Notes

  • Cast speakers do not support crossfading of audio. If you want crossfade and/or full gapless support, enable the "flow mode" in the player's advanced settings. Enabling flow mode may solve playback issues however it might come with the side effect of disabling actual physical buttons and/or display of metadata on the device itself
  • If your Chromecast speakers are not auto detected or randomly unavailable then make sure that your Cast enabled speakers are on the same network/subnet as your Music Assistant server. Additionally, ensure that multicast traffic (more specifically mDNS) can travel freely as that is used for the discovery of players
  • After re-enabling a disabled speaker, it can take a while before the speaker is rediscovered, the process can be sped up by restarting Music Assistant
  • It is possible to group cast players via a Universal Group although they may not play in sync
  • TV/Video devices (not the AV dongles) are disabled by default
  • Cast Groups containing only a stereo pair will not work
