The problem

This has existed for a while now; only just now troubleshooting/reporting it.

CCast Speaker Groups raise volume for Announcements when music is actively playing to the Group. All CCast speakers within the Group have the Announcement options set to Do Not Adjust Volume. Groups don't have any such volume adjustment options, which appears to throw a traceback in the logs when an Announcement is sent. So, CCast Groups shouldn't be raising or adjusting the volume for Announcements (except perhaps where specific speakers have this option set?).

May the attached log light your way. 😁

How to reproduce

1. Ensure all Chromecast individual speakers are set to Do Not Adjust Volume for Announcements.

2. Play music to a Chromecast Group that includes only the speakers with Do Not Adjust Volume set.

3. Send Announcement (tts.cloud_say or tts.speak) to Group (or any speaker within the Group)

Announcement routine will raise volume on the Speakers, play announcement, lower volume, then resume playing music. The behavior appears similar to the default Announcement options for individual players, despite such options not existing for CCast Groups.

Additional information

I am sending Announcements via the tts.cloud_say action, not the music_assistant.play_announcement action, as I am dynamically generating audio from Assist responses and other automations. I am not using the Pre-Announcement sound at all anywhere.
