Grouped speakers play sound out-of-sync | SoundTouch® 10 wireless speaker
If grouped sound is out-of-sync:
Try the following:
If the grouping was created in the Bose app, turn the SoundTouch speaker off then back on.
Turning the speaker off will end the group. Once the speaker is back on, create the group again in the Bose Music app.
If you want to play the same sound on all systems, use the Play Everywhere option.
Play Everywhere lets all systems on your account play the same sound in sync. When not using this option and instead selecting the same stream on each system, each system plays an independent instance of that stream, which may not play in sync. For more info, see Grouping systems.
If rebroadcasting a wired video source, use the Video Sync setting to to sync audio among the grouped systems.
If your system is the host/main system in a group of Bose speakers and it is broadcasting sound from a video source (e.g. cable box) to the group, adjust the host system sync setting in the Bose app.
If playing an Amazon Alexa source, use the Bose SoundTouch Control skill for group playback.
Amazon Alexa cannot play the same audio stream on multiple speakers. If you ask Alexa to play content on one speaker and then ask Alexa to play that same content on another speaker, Alexa will send a separate stream to both speakers. Playing content in unison on multiple speakers is a feature of SoundTouch, which requires the Bose SoundTouch Control skill. For more info see, Setting up the Bose Skills for Amazon Alexa and Controlling SoundTouch systems using the Bose Skills for Amazon Alexa.
If playing from a group of AirPlay speakers, check if there is a mix or AirPlay 1 and AirPlay 2 speakers in the group.
If you have some speakers that support AirPlay 1 and some that support AirPlay 2, you can play them together as an AirPlay group by streaming via AirPlay 1 rather than AirPlay 2. When playing older and newer system together this way, audio among the systems might be out of sync. For multi-room sound that plays in-sync, group only AirPlay 2-compatible products.
Reboot your router.
Routers may need to be reset from time to time—much like rebooting a computer. Disconnect power from the router for 30 seconds, then wait for it to start up and connect. (Note: Any device connected to the Internet will be interrupted during the reset.)
