Sonos 'extra' for Announce volume no longer reliable

Since 2024.7.0 or possibly 2024.7.1, when specifying volume using extra, the media does not play dependably. In my case this is a doorbell chime. When the doorbell is triggered, the media seems to play on some but not all media players and at a very faint volume. My chime is 3 seconds long. For 0.5 second the volume seems to be correct but the remaining is cut dramatically.

If I remove the extra arguments, all works well again, but this is not an ideal config for me.

My automation has been solid and has not changed in months and seems to have started since one of the July HA update.
