Snapcast integration - speaker source not being captured during snapshot or restore?

[mental vector]

Hello - I just integrated my snapcast server with Home Assistant. I am able to control my 3 snapcast speakers, and was trying to set up some automations with the 'snapcast.snapshot' and 'snapcast.restore' service calls. Reviewing the info logs, only volume and muted attributes are being snapshotted/restored:

I was under the impression that each speaker's stream source would be captured/restored using these service calls

should I file a github issue?
