New feature

Support a default volume for audio clip playback by using the volume slider on the media_player entity. If set to 0 (the default), the current volume on the speaker will be used. The per-call override will still be used if provided.

See https://github.com/jjlawren/sonos_cloud#volume-control for more details.

Note: Support for TTS volume support will be possible in a future release along with a new feature in Home Assistant 2022.3. 🎉
