Ability to switch current playback/queue from speaker to speaker

[fernplant]

This is a feature I miss from using Amazon Music or other Google cast-able apps. I can't switch from one speaker (or group) to another while music is playing and have it pick back up wherever it was already at

Love this project, use it everyday now. Thank you

Spotify itself allows for something similar when ungrouping speakers I get the option to resume playback.
It would be nice to have the option to move the active output to a different speaker.
This would further improve the use case for people with multiple speaker systems.

It probably could be used to create a 'music walk with me' automation where play moves to mobile phone output when leaving the house and then back to the speaker system upon return. At the very least it may make writing such a script easier ...

Would be great to have the ability to transfer music/queue playing on one speaker/speaker group in Music Assistant to another speaker/speaker group. This would be similar to stream transfer functionality in the Google Home app for Chromecast speakers.

Absolutely love Music Assistant for Home Assistant. For me, it was the missing "killer app" for Home Assistant.

I believe this is already possible. If you cast to a group then turn down the volume of all the speakers where you aren’t aren’t. When you move turn up that speaker and turn down the other.

This isn't exactly the functionality I was describing, but is a really interesting work-around in the interim. The functionality that I was describing is essentially what the Google Home app provides (the ability to select or deselect speakers for the currently playing media source. Described further in this HA forum: Google Cast Media Transfer From One Speaker To Another in Home Assistant. Will give your suggestion a try, as I think similar functionality could be simulated via multiple automations triggered by Lovelace buttons. Thank you.

I explored this over the weekend and realized that there are a couple of significant limitations to the "whole house" cast group and automations to mute or turn up volume approach. Specifically, it would take over my Chromecast enabled AV receiver any time I play music. If someone else is watching the television (connected to the receiver) it would switch the input from video source to Chromecast, resulting in the inability to watch a movie in one room and listen to music in another. Another limitation, which could potentially be worked around with even more automations is the ability to play from two different music sources on different Chromecast speakers in different rooms.

Here's how I solved it:

• have a cast group per floor (or section you play at the same time)
• for the section that includes the AV receiver just have another group with the rest of the speakers, excluding the AV receiver.
• create a HA group with all cast groups (yes you can have groups within groups)
• maintain the queue on that "whole house" HA group player
• Use your automations to turn "on" the right cast group player.

A few tricks:

• You can just use the turn on/off controls on the underlying "child" players, MA will automatically translate that into a mute command.
• If you turn off the last child of a group, MA will auto turn off the cast group
• If you turn off the last cast group player, MA will automatically turn off the "whole house" group player.

So, to sum up;

• I have an automation per speaker to turn it on/off and set the correct volume based on time of the day, motion etc.
• I have a script to turn on the (correct) cast group player.
• I have an automation to fill the queue of the "whole house" player during the day with playlists suitable for the time of day.

In the end a lot of workarounds but it works pretty great actually. The best would be if we can group/ungroup cast speakers from MA and service calls but Google did not yet expose an api for that.

Thank you for the detailed workaround instructions. I will give it a try. If I'm following correctly, this is the key functionality that will prevent my AV receiver from switching over (assuming it is part of a group that is turned off): "If you turn off the last child of a group, MA will auto turn off the cast group". Would you be able to share the scrip to turn on cast group players?

Is this a duplicate of #553 ?

[OzGav]

Yes pretty much...
