I write exactly the same kind of automation with Home Assistant and I use the first player of the sonos_group list as group master which make things much easier
I did the same thing. However, I improved it by setting up the second player of the sonos_group list as group master if I leave the room that is the current group master. So the group master actually leave the group. See the code of " # Update the master speaker in the group" for details
Thanks for this, but one question from a noob 
Where do I put all this code? I already realized the Sonos integration with the mini media player, but I am not really satisfied as the functionality is really minimized.
You need to put these as part of your automation.yaml and script.yaml and include them from your configuration.yaml like this
automation: !include automation.yaml
script: !include script.yaml
See Automation YAML - Home Assistant for reference.
You will also need to update my automation with your devices but I think you can directly use the script.
does this still work with 2022.5? Since this update they removed sonos_group and now my own way of grouping (or at least, detecting the group) is not working anymore, and since this has been a long time since I have set it up, I am not sure how to fix this 
I had this done with a custom sensor that used the sonos_group as value_template:
{%- for player in states.media_player if player.attributes.sonos_group %}
{%- if player.attributes.sonos_group[0] == player.entity_id %}
{%- set slaves = player.attributes.sonos_group[1:] %}
{{ slaves|join(",")|replace("media_player", "input_boolean") }}
{%- endif %}
{%- endfor %}
but in 2022.5 they changed sonos_group for group_members, and somehow neither now work with this…
The sonos_group attribute was renamed and is now called group_members. Adjust your template accordingly.
{%- for player in states.media_player if player.attributes.group_members is defined %}
{%- if player.attributes.group_members[0] == player.entity_id %}
{%- set slaves = player.attributes.group_members[1:] %}
{{ slaves|join(",")|replace("media_player", "input_boolean") }}
{%- endif %}
{%- endfor %}
thx! I tried that but it didn’t work, but seems I was missing the is defined part 
If you have non-Sonos media_players, states.media_player will include them. However, you will get an error if you attempt to access the group_members attribute for a media_player that doesn’t have it. That’s why the for reduces the list of media_players to only those that have the group_members attribute defined.
{%- for player in states.media_player if player.attributes.group_members is defined %}
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Another way of doing the same thing:
{%- for player in states.media_player | selectattr('attributes.group_members', 'defined') | list %}
thx for the explanation!
Thanks guys for spotting this as well. I just updated to this month release and realised this automation was broken due to this.
Hey @relliky , is your config on github working after the update? Mine has gone to crap and i can’t workout why so will probably start from scratch if its working for you
Thanks
The latest release, version 2022.8.0, eliminated service calls sonos.join and sonos.unjoin. The replacements are media_player.join and media_player.unjoin.
The script in the original post needs modification in order to work with 2022.8.0.
Hey @123 i had already updated the media_player.join options but still not wokring anymore. Im getting an error in the logs saying:

The problem is identified in the error message:
extra keys not allowed @ data[‘master’]
master is not a valid option for media_player.join. You’re using the options that were valid for sonos.join but they’re different for media_player.join.
service: media_player.join
target:
entity_id: "media_player.{{ states('input_select.music_controller') }}"
data:
group_members: "{{ target_player if target_player is not none else media_player.lounge }}"
That worked! Thanks heaps 
Hello friends,
I hope you can help me. I tried to install the whole thing at HA.
I have adapted the script to my player as far as I can see. However, I keep getting an error when I run it. I’m fairly new to HA.

I think (not sure) you need to outdent the data key, like this:

Hey guys, so in the future here 2023 and trying to get this script to work. It’s not going well…
Can someone confirm this script still works with todays HA build? Changed sonos service calls to media_player but it’s still giving errors out. If someone has this working today I’ll keep going trying to figure this out, if not, I’ll find another solution.
I never quite understood why there is need for “master speaker variable” and it’s maintenance every 5 mins. Maybe I’m missing something, but this is my automation which does basically the same as the scripts in OP, but without that variable. It allows to set “volume offsets” for different speakers, and doesn’t join living room speaker to others when watching TV (however, it joins the other way - if you’re watching TV and go to kitchen for drink, kitchen speaker joins and you’ll hear TV there).

Hey Tomas1, thanks. That is very helpful. I think the master variable is to keep the audio consistent throughout the rooms, so that if you walk into room 3 for example it will play the audio of the master controller and wont start playing whatever was playing last on that particular speaker, and it gets the audio levels from the master, but I agree there is better way to do that now as the media_player service seems more robust then it was 2 years ago.
Care to post your input_boolean, input_select, scripts, and automations yaml files? I’m not having any luck with what I have found thus far. Thanks in advance
