Feature request: volume state/level #10

Do you think there's a way to get the volume level (and possibly set a volume level)?

Most of my other media players in Home Assistant have a volume_level attribute. I don't see that for a Shairport Sync media player:

However, when I change the volume of the Shairport Sync instance (via my iPhone, for instance), I see this on the MQTT topic:

Pressing volume up and it looks like this: image

I don't know what these numbers mean, but do you think they could be used to drive a volume_level attribute in HA?

Shairport Sync does report a volume level via MQTT, but doesn't support setting an explicit volume.

From the experimentation I did, HA will only display a volume slider if the media player can set an arbitrary volume.

Appears there might be some technical limitations: https://github.com/mikebrady/shairport-sync/issues/773

Yeah, when I built this I looked into this, but it didn't seem feasible. There are various volume controls involved. I couldn't think of a decent workaround, so stuck with relative volume setting. If someone has a solid implementation and wants to provide it as a PR, I'm obviously open to that. For now, I'll close it.
