I am new with HASS.
My auto discovery finds my bluesound speaker and also show what currently playing without problems but the problems is that the controls dont work.
Every second weekend there is a new release of HA, so expect a new version this Sunday (or maybe even Saturday).
I don’t know how you installed HA on your synology device, but if you followed the guide here you have the command to upgrade at the bottom of the page.
On the docker installation page you can read this, it should work. As I said, I don’t use Synology and I can’t help you further…
Remark: to update your Home Assistant on your Docker within Synology NAS, you just have to do the following:
Go to the Docker-app and move to “Image”-section
Download the “homeassistant/home-assistant” image - don’t care, that it is already there
wait until the system-message/-notification comes up, that the download is finished (there is no progress bar)
Move to “Container”-section
Stop your container if it’s running
Right-click on it and select “Action”->”Clear”. You won’t lose any data, as all files are stored in your config-directory
Start the container again - it will then boot up with the new Home Assistant image
